This book is about algebraic and differential methods, as well as fractional calculus, applied to diagnose and reject faults in nonlinear systems, which are of integer or fractional order. This represents an extension of a very important and widely studied problem in control theory, namely fault diagnosis and rejection (using differential algebraic approaches), to systems presenting fractional dynamics, i.e. systems whose dynamics are represented by derivatives and integrals of non-integer order. The authors offer a thorough overview devoted to fault diagnosis and fault-tolerant control applied to fractional-order and integer-order dynamical systems, and they introduce new methodologies for control and observation described by fractional and integer models, together with successful simulations and real-time applications. The basic concepts and tools of mathematics required to understand the methodologies proposed are all clearly introduced and explained. Consequently, the book is useful as supplementary reading in courses of applied mathematics and nonlinear control theory. This book is meant for engineers, mathematicians, physicists and, in general, to researchers and postgraduate students in diverse areas who have a minimum knowledge of calculus. It also contains advanced topics for researchers and professionals interested in the area of states and faults estimation.

A poetical trip across the seasons, some different landscapes, and the experience of become a father. "Son" is a personal interpretation of the haiku/senryu that looks for his root in view of the Zen one -simple and daily meditation- without resigning from a Mediterranean influence, images and traditional metaphor in the Spanish poetry. Illustrated like a modern "haiga," his snapshots invite to stop to listen to the silent dialogue between our interior voice and the nature.

This book provides a general overview of several concepts of synchronization and brings together related approaches to secure communication in chaotic systems. This is achieved using a combination of analytic, algebraic, geometrical and asymptotical methods to tackle the dynamical feedback stabilization problem. In particular, differential-geometric and algebraic differential concepts reveal important structural properties of chaotic systems and serve as guide for the construction of design procedures for a wide variety of chaotic systems. The basic differential algebraic and geometric concepts are presented in the first few chapters in a novel way as design tools, together with selected experimental studies demonstrating their importance. The subsequent chapters treat recent applications. Written for graduate students in applied physical sciences, systems engineers, and applied mathematicians interested in synchronization of chaotic systems and in secure communications, this self-contained text requires only basic knowledge of integer ordinary and fractional ordinary differential equations. Design applications are illustrated with the help of several physical models of practical interest.

This book acquaints readers with recent developments in dynamical systems theory and its applications, with a strong focus on the control and estimation of nonlinear systems. Several algorithms are proposed and worked out for a set of model systems, in particular so-called input-affine or bilinear systems, which can serve to approximate a wide class of nonlinear control systems. These can either take the form of state space models or be represented by an input-output equation. The approach taken here further highlights the role of modern mathematical and conceptual tools, including differential algebraic theory, observer design for nonlinear systems and generalized canonical forms.

The high reliability required in industrial processes has created the necessity of detecting abnormal conditions, called faults, while processes are operating. The term fault generically refers to any type of process degradation, or degradation in equipment performance because of changes in the process's physical characteristics, process inputs or environmental conditions. This book is about the fundamentals of fault detection and diagnosis in a variety of nonlinear systems which are represented by ordinary differential equations. The fault detection problem is approached from a differential algebraic viewpoint, using residual generators based upon high-gain nonlinear auxiliary systems ('observers'). A prominent role is played by the type of mathematical tools that will be used, requiring knowledge of differential algebra and differential equations. Specific theorems tailored to the needs of the problem-solving procedures are developed and proved. Applications to real-world problems, both with constant and time-varying faults, are made throughout the book and include electromechanical positioning systems, the Continuous Stirred Tank Reactor (CSTR), bioreactor models and belt drive systems, to name but a few.

This book addresses the problem of multi-agent systems, considering that it can be interpreted as a generalized multi-synchronization problem. From manufacturing tasks, through encryption and communication algorithms, to high-precision experiments, the simultaneous cooperation between multiple systems or agents is essential to successfully carrying out different modern activities, both in academy and industry. For example, the coordination of multiple assembler robots in manufacturing lines. These agents need to synchronize. The first two chapters of the book describe the synchronization of dynamical systems, paying special attention to the synchronization of non-identical systems. Following, the third chapter presents an interesting application of the synchronization phenomenon for state estimation. Subsequently, the authors fully address the multi-agent problem interpreted as multi-synchronization. The final chapters introduce the reader to a more complex problem, the synchronization of systems governed by partial differential equations, both of integer and fractional order. The book aimed at graduates, postgraduate students and researchers closely related to the area of automatic control. Previous knowledge of linear algebra, classical and fractional calculus is requested, as well as some fundamental notions of graph theory.

After a short introduction to the fundamentals, this book provides a detailed account of major advances in applying fractional calculus to dynamical systems. Fractional order dynamical systems currently continue to gain further importance in many areas of science and engineering. As with many other approaches to mathematical modeling, the first issue to be addressed is the need to couple a definition of the fractional differentiation or integration operator with the types of dynamical systems that are analyzed. As such, for the fundamentals the focus is on basic aspects of fractional calculus, in particular stability analysis, which is required to tackle synchronization in coupled fractional order systems, to understand the essence of estimators for related integer order systems, and to keep track of the interplay between synchronization and parameter observation. This serves as the common basis for the more advanced topics and applications presented in the subsequent chapters, which include an introduction to the 'Immersion and Invariance' (I&I) methodology, the masterslave synchronization scheme for partially known nonlinear fractional order systems, Fractional Algebraic Observability (FAO) and Fractional Generalized quasi-Synchronization (FGqS) to name but a few. This book is intended not only for applied mathematicians and theoretical physicists, but also for anyone in applied science dealing with complex nonlinear systems.

Mi certeza mas remota es una plaza donde daba canamon a las palomas, unos pantalones acampanados, a cuadros, que ocultaban unas botas insufribles, ratos en el suelo de la terraza embobado con las nubes, o con los itinerarios de las hormiguitas entre las macetas, el aroma de la flor mas pequena en una de las plantas, con sus frutos rojos, Cleopatra y Tarzan en blanco y negro con galletitas melosas, en forma de corazon, las tardes de invierno, mientras mi madre cosia y sobrehilaba secuestrada por el ritmo trepidante de la Refrey, y las salidas y llegadas de los trenes, hora tras hora, dia tras dia...Pero el sabor mas dulce de una infancia mohina y solitaria, el quid de la cuestion que anos despues siempre me he preguntado, se escondia lejos de mi casa.

This book is a short primer in engineering mathematics with a view on applications in nonlinear control theory. In particular, it introduces some elementary concepts of commutative algebra and algebraic geometry which offer a set of tools quite different from the traditional approaches to the subject matter. This text begins with the study of elementary set and map theory. Chapters 2 and 3 on group theory and rings, respectively, are included because of their important relation to linear algebra, the group of invertible linear maps (or matrices) and the ring of linear maps of a vector space. Homomorphisms and Ideals are dealt with as well at this stage. Chapter 4 is devoted to the theory of matrices and systems of linear equations. Chapter 5 gives some information on permutations, determinants and the inverse of a matrix. Chapter 6 tackles vector spaces over a field, Chapter 7 treats linear maps resp. linear transformations, and in addition the application in linear control theory of some abstract theorems such as the concept of a kernel, the image and dimension of vector spaces are illustrated. Chapter 8 considers the diagonalization of a matrix and their canonical forms. Chapter 9 provides a brief introduction to elementary methods for solving differential equations and, finally, in Chapter 10, nonlinear control theory is introduced from the point of view of differential algebra.

By embedding Guatemala in recent conceptual and theoretical work in comparative politics and political economy, this volume advances knowledge about country’s politics, economy, and state-society interactions. The contributors examine the stubborn realities and challenges afflicting Guatemala during the post-Peace-Accords-era across the following subjects: the state, subnational governance, state-building, peacebuilding, economic structure and dynamics, social movements, civil-military relations, military coup dynamics, varieties of capitalism, corruption, and the level of democracy. The book deliberately avoids the perils of parochialism by placing the country within larger scholarly debates and paradigms.

Are interactions between soldiers, politicians, and civilians improving? Every nation has to come to grips with achieving a more enduring harmony between government, the armed forces, and society if it aspires to strengthen its democracy. While there is an abundance of studies on civil-military affairs, few examine all three of these actors, let alone establish any standards with which to assess whether progress is being made. This ambitious book devises a novel framework equipped with six dimensions, each of which opens a unique window into civil-military affairs, and which form a more integrated view of the subject. Those dimensions are accompanied by a set of benchmarks and metrics that assess progress and compare one country against another. The framework is applied to case studies of Argentina, Brazil, Chile, and Uruguay, with the conviction that insights could be gleaned that may be relevant elsewhere. Ultimately, by unpacking the civil-military relation into its various dimensions, this study has shed light on what it takes to transform what was once a politically-minded military into an organization dedicated to serving a democratic state and society.

The study of civil-military relations in Latin America produced a rich debate and research agenda prior to 2000. But this agenda was largely abandoned during the past decade as the spectre of military dictatorship has virtually disappeared, with the political role of the military in many countries dramatically diminished. Indeed, in no country that has initiated a process of holding the military accountable to civilian control has the military openly rebelled. Yet, the institutions and public attitudes that guarantee democratic civilian control of the military exist in a general context of political polarisation, citizen insecurity and in many countries a sense of developing ungovernability. The military coup in Honduras (2009), the military response to the police rebellion in Ecuador (2010), and the speculation concerning the Venezuelan military's behaviour in the event that Hugo Chavez is incapacitated or dies (2013), demonstrates the relevance and importance of the civil-military relationship today. In this volume leading scholars from Latin America, the U.S. and Spain debate the ability of contemporary Latin American civil-military relationships to weather these challenges. The authors examine new types of regimes (the rise of participatory democracy), new political orientations (the renaissance of the Left in Latin America), and new missions for the military. Debate centres on the indicators to evaluate the level of consolidation of civilian control, the manner in which these indicators are measured, and the empirical ambiguities that arise. These challenges must be confronted in order to effectively address the question of how much progress has been made in the region in subordinating the military to civilian control, which countries are lagging behind, and why.
