This book presents comprehensive information on the relay auto-tuning method for unstable systems in process control industries, and introduces a new, refined Ziegler-Nichols method for designing controllers for unstable systems. The relay auto-tuning method is intended to assist graduate students in chemical, electrical, electronics and instrumentation engineering who are engaged in advanced process control. The book's main focus is on developing a controller tuning method for scalar and multivariable systems, particularly for unstable processes. It proposes a much simpler technique, avoiding the shortcomings of the popular relay-tuning method. The effects of higher-order harmonics are incorporated, owing to the shape of output waveforms. In turn, the book demonstrates the applicability and effectiveness of the Ziegler-Nichols method through simulations on a number of linear and non-linear unstable systems, confirming that it delivers better performance and robust stability in the presence of uncertainty. The proposed method can also be easily implemented across industries with the help of various auto-tuners available on the market. Offering a professional and modern perspective on profitably and efficiently automating controller tuning, the book will be of interest to graduate students, researchers, and industry professionals alike.

Loosely speaking, adaptive systems are designed to deal with, to adapt to, chang ing environmental conditions whilst maintaining performance objectives. Over the years, the theory of adaptive systems evolved from relatively simple and intuitive concepts to a complex multifaceted theory dealing with stochastic, nonlinear and infinite dimensional systems. This book provides a first introduction to the theory of adaptive systems. The book grew out of a graduate course that the authors taught several times in Australia, Belgium, and The Netherlands for students with an engineering and/or mathemat ics background. When we taught the course for the first time, we felt that there was a need for a textbook that would introduce the reader to the main aspects of adaptation with emphasis on clarity of presentation and precision rather than on comprehensiveness. The present book tries to serve this need. We expect that the reader will have taken a basic course in linear algebra and mul tivariable calculus. Apart from the basic concepts borrowed from these areas of mathematics, the book is intended to be self contained."

The impact of control system design on ship performance has been significant in different applications of ship motion control: course keeping, station keeping, roll stabilisation and vertical motion/riding control, diving, path following, etc. This monograph introduces ship motion control by studying the particular problems of control system design for course autopilots with rudder roll stabilisation and combined ruddera "fin stabilisers. Ship Motion Control revisits the ingredients that make these control designs challenging and proposes a contemporary control system design approach to meet that challenge.

The key ingredients for a successful ship motion control system design are:

• appropriate mathematical models of the ship and the disturbances;
• understanding of how performance will be assessed;
• knowledge of fundamental limitations that may prevent designs from achieving the desired performance.

The book is organised in four parts, the first three dealing with each of these and the fourth part addressing control system design.

Specific topics covered include:

• modelling and simulation of ocean waves;
• ship dynamics;
• models of actuators;
• ship roll stabilisation devices;
• ship motion performance;
• analysis of fundamental limitations for stabiliser control system design;
• constrained control design via optimisation;
• autopilot design using optimal control;
• wave filtering;
• control system design for autopilots with rudder roll stabilisation;
• control system design for integrated rudder-fin stabiliser.

Ship Motion Control willbe of interest not only to the practising marine engineer but to the academic engaged in research into this important control problem, even if new to the area. It will also be an ideal source of reference for students and tutors involved with marine and control engineering courses.

Can psychoanalysis offer a new computer model? Can computer designers help psychoanalysts to understand their theory better?In contemporary publications human psyche is often related to neural networks. Why? The wiring in computers can also be related to application software. But does this really make sense?

Artificial Intelligence has tried to implement functions of human psyche. The reached achievements are remarkable; however, the goal to get a functional model of the mental apparatus was not reached. Was the selected direction incorrect?The editors are convinced: yes, and they try to give answers here. If one accepts that the brain is an information processing system, then one also has to accept that computer theories can be applied to the brain s functions, the human mental apparatus.

The contributors of this book - Solms, Panksepp, Sloman and many others who are all experts in computer design, psychoanalysis and neurology are united in one goal: finding synergy in their interdisciplinary fields."

We live in an ever complex, dynamic and technological-based world. A world where industries, businesses and agencies rely ever increasingly on automated systems to maintain efficiency, increase productivity, minimize human error or gain a competitive edge. Moreover, automation is now seen by many organizations as the solution to human performance problems. These organizations continue to invest significant resources to implement automated systems wherever possible and there is no doubt that automation has helped such organizations manage their sophisticated, information-rich environments, where humans have limited capabilities. Therefore, automation has helped to improve industrial and commercial progress to the extent that organizations now depend upon it for their own benefit. However, new and unresolved problems have arisen as more individuals, groups and teams interact with automated systems. Hence, the need and motivation of this volume. The chapters contained in this volume explore some of the key human performance issues facing organizations as they implement or manage automated systems. Dealing with a range of topics, from how to design optional use, avoiding misuse, to creating training strategies for automated systems, this volume also explores which theories may help us understand automation better and what research needs to be conducted. This publication attempts to illustrate how human performance research on automation can help organizations design better systems and also hopes to motivate more theoretically-based but practically-relevant research in the technological-based world of the 21st century.

A discussion of challenges related to the modeling and control of greenhouse crop growth, this book presents state-of-the-art answers to those challenges. The authors model the subsystems involved in successful greenhouse control using different techniques and show how the models obtained can be exploited for simulation or control design; they suggest ideas for the development of physical and/or black-box models for this purpose. Strategies for the control of climate- and irrigation-related variables are brought forward. The uses of PID control and feedforward compensators, both widely used in commercial tools, are summarized. The benefits of advanced control techniques-event-based, robust, and predictive control, for example-are used to improve on the performance of those basic methods. A hierarchical control architecture is developed governed by a high-level multiobjective optimization approach rather than traditional constrained optimization and artificial intelligence techniques. Reference trajectories are found for diurnal and nocturnal temperatures (climate-related setpoints) and electrical conductivity (fertirrigation-related setpoints). The objectives are to maximize profit, fruit quality, and water-use efficiency, these being encouraged by current international rules. Illustrative practical results selected from those obtained in an industrial greenhouse during the last eight years are shown and described. The text of the book is complemented by the use of illustrations, tables and real examples which are helpful in understanding the material. Modeling and Control of Greenhouse Crop Growth will be of interest to industrial engineers, academic researchers and graduates from agricultural, chemical, and process-control backgrounds.

One of the main goals of optimal control theory is to provide a theoretical basis for choosing an appropriate controller for whatever system is under consideration by the researcher or engineer. Two popular norms that have proved useful are known as H-2 and H - infinity control. The first has been particularly applicable to problems arising in the aerospace industry. However, most industrial problems are badly modeled and the second norm proved to be more appropriate when the actual conditions of the problem did not conform to the stipulated conditions of the theory. This book takes the topic of H-infinity control as a point of departure and pursues an improved controller design which has been suggested in the mainstream of robust control. Its main theme, minimum entropy control, provides a means of trading off some of the features of other control problems. The book is aimed at research workers in networking systems as well as those in operator theory and linear multivariable control. The use of stochastic methods makes the book also of importance to the circuits and systems community.

Very often, practical design of embedded systems lacks consistency resulting in computer control systems that do not provide the performance they should. Most notably they lack dependability, a key property now that programmed electronic devices are so pervasive, even in extremely safety-critical applications. Distributed Embedded Control Systems handles the domains encountered when designing a distributed embedded computer control system as an integrated whole. First to be discussed are some basic issues about real-time systems and their properties, specifically safety. Then, system and hardware architectures are dealt with: areas like scheduling, asymmetrical distributed multiprocessor architectures, time-triggered communications, middleware, fault-tolerant peripherals, etc. Next, programming issues, embodying desired properties, basic language subsets, object orientation and language support for hardware and software specifications and co-design are elaborated and finally, the prototype implementation of a distributed embedded control system is given as a detailed example. Different audiences will find much of interest in this work: industrial professionals are given guidelines for the design of embedded hardware and software with fault tolerance that will help them to decide which methods, tools and solutions they should employ and to which features they should pay attention. Academics have a new source of solutions and further questions to stimulate research and it will also be informative for graduate students in electrical, control and computer engineering.

Model based fuzzy control uses a given conventional or fuzzy open loop model of the plant under control to derive the set of fuzzy if-then rules for the fuzzy controller. Of central interest are the stability, performance, and robustness properties of the resulting closed loop system involving a conventional or fuzzy model and a fuzzy controller. The major objective of model based fuzzy control is to use the full range of linear and nonlinear design and analysis methods to design such fuzzy controllers with properties superior to non-fuzzy controllers designed using the same techniques. This objective has already been achieved for fuzzy sliding mode controllers and fuzzy gain schedulers - the main topics of this book. A comprehensive and up-to-date treatment of model based fuzzy control and its relationship to conventional control, the text is intended to serve as a guide for scientists and practitioners and to provide introductory material on fuzzy control for courses in control theory.

Hybrid supervisory systems integrate and exchange information between discrete- and continuous-data-based controllers and subsystems. Application areas include process, manufacturing and service industries, healthcare, telecommunication, transportation and logistics, among others.

From the hardware point of view, the rapid progress of information-processing power and its commercial availability has made possible the development of complex supervisory systems. Many barriers that restrained the evolution of supervisory systems in the past have been removed by the recent popularisation of the open-system paradigm. On the other hand, software has not followed the evolution in hardware and both the industrial and scientific communities have pointed out the need for a generic approach that guides the development of hybrid supervisory systems.

Modelling and Analysis of Hybrid Supervisory Systems introduces a modelling formalism that merges Petri nets, differential equation systems and object-oriented methods; a formalism that is adequate for modelling complex and large-scale systems. To guide the designer and conduct hybrid modelling, the book describes a method that starts from the requirements of a supervisory system and results in a proposal for such a system. The method is mainly based on Unified Modelling Language diagrams, well-known tools in both academia and industry. In order to ensure that the supervisory system will behave as expected under any operational circumstances, a validation procedure that allows verification of the formal properties of the hybrid model is presented.

In building a bridge between what is developed in academic research and what is available to theindustrial professional, this monograph places particular emphasis on the description of real-world examples; three of these a" an HVAC management system, a landing system and a cane-sugar factory a" are discussed at length.
