An unmanned aerial vehicle (UAV) is an aircraft that is equipped with necessary data processing units, sensors, automatic control and communications systems, and is capable of performing autonomously flight missions without a human pilot. Unmanned Rotorcraft Systems provides a complete treatment of the design of fully autonomous miniature rotorcraft UAVs. It is an integration of advanced technologies developed in communications, computing and control areas. In particular, it focuses on:

the systematic hardware construction;

software systems integration;

aerodynamic modeling; and

automatic flight control system design.

Emphasis is extended to the cooperative control and flight formation of multiple UAVs, and vision-based ground target tracking and landing on moving platforms. Other issues such as the development of GPSless indoor micro aerial vehicles and vision-based navigation are also highlighted.

The proposed monograph aims to explore the research and development of fully functional miniature UAV (unmanned-aerial-vehicle) rotorcraft. This consists of a small-scale basic rotorcraft with all necessary accessories onboard, and a ground station. The unmanned system is an integration of advanced technologies developed in communications, computing and control areas. It is an excellent testing ground for trialing and implementing modern control techniques. It is however a highly challenging process. The aerodynamics of a small-scale rotorcraft such as a hobby helicopter are similar to its full-scale counterpart but has some unique characteristics, such as the utilization of stabilizer bar and higher main/tail rotors rotation speed. Besides these, the strict limitation on payload also increases the difficulty on upgrading a small-scale rotorcraft to a UAV with full capacities. Based on its various characteristics and limitations, a light-weight but effective onboard computer system with corresponding onboard/ground software should be carefully designed to realize the system identification and automatic flight requirements. These issues will be addressed in detail in this monograph. Research on the following will be detailed:

utilizing the vision-based system for accomplishing ground target tracking;

attacking and landing;

cooperative control and flight formation of muitiple unmanned rotorcraft;

future research directions on the related areas.

The book will be a good reference for researchers and students working on the related subjects. Unmanned Rotorcraft Systems will be of great value to practicing engineers in rotorcraft industries and to researchers in areas related to the development of unmanned systems in general. It may be used as a reference for advanced undergraduate and graduate students in aeronautics and astrinautics, electrical and mechanical engineering."

The second edition of this monograph provides a systematic treatment of the design of modern hard disk drive servo systems updated with the latest research results to reflect recent improvements in spindle speed and bit density and other changes in this fast-moving field. In particular, it focuses on the applications of some newly developed results in control theory, i.e., robust and perfect tracking control and composite non-linear feedback control which are suitable for track following and seeking respectively. Emphasis is placed on hard disk drive servo systems with single- or dual-stage actuation using a voice-coil-motor actuator enhanced in the latter case by the addition of a micro-actuator providing faster responses and therefore higher bandwidth in track following. Other issues such as modeling and compensation of nonlinearities and friction in microdrives, disturbance rejection and resonance compensation are also addressed.

The techniques and applications involved include:

• time- and frequency domain methods for system identification;
• physical effect approaches for parameter identification;
• linear systems tools;
• linear control techniques (PID, H2, H-infinity, and other robust control methods);
• classical nonlinear control techniques (time-optimal, proximate time-optimal, and mode switching control);
• composite nonlinear feedback (CNF) control;
• complete single- and dual-stage hard disk drive servo systems;
• time- and frequency domain properties of hard disk drive servo systems;
• design of piezoelectric actuator systems;
• modeling and compensation of nonlinearities and friction inmicrodrives.

Hard Disk Drive Servo Systems will be of great value to practicing engineers in the hard disk and CD-ROM drive industries and to researchers in areas related to servo systems. The Linear Systems and CNF MATLABA(R) toolkits used to develop many of the results in this book can be downloaded from Professor Chena (TM)s website.

The series Advances in Industrial Control aims to report and encourage technology transfer in control engineering. The rapid development of control technology has an impact on all areas of the control discipline. New theory, new controllers, actuators, sensors, new industrial processes, computer methods, new applications, new philosophies , new challenges. Much of this development work resides in industrial reports, feasibility study papers and the reports of advanced collaborative projects. The series offers an opportunity for researchers to present an extended exposition of such new work in all aspects of industrial control for wider and rapid dissemination. Hard disk drive systems are ubiquitous in today's computer systems and the technology is still evolving. There is a review of hard disk drive technology and construction in the early pages of this monograph that looks at the characteristics of the disks and there it can be read that: "bit density... continues to increase at an amazing rate", "spindle speed... the move to faster and faster spindle speeds continue", "form factors... the trend...is downward... to smaller and smaller drives", "performance... factors are improving", "redundant arrays of inexpensive disks... becoming increasingly common, and is now seen in consumer desktop machines", "reliability... is improving slowly... it is very hard to improve the reliability of a product when it is changing rapidly" and finally "interfaces... continue to create new and improved standards... to match the increase in performance of the hard disks themselves".
