When choosing the technology options to develop a wireless sensor network (WSN), it is vital that their performance levels can be assessed for the type of application intended. This book describes the different technology options - MAC protocols, routing protocols, localisation and data fusion techniques - and provides the means to numerically measure their performance, whether by simulation, mathematical models or experimental test beds. Case studies, based on the authors' direct experience of implementing wireless sensor networks, describe the design methodology and the type of measurements used, together with samples of the performance measurements attained.

The book will enable you to answer vital questions such as:

* How long will my network remain alive given the amount of sensing required of it?
* For how long should I set the sleeping state of my motes?
* How many sensors should I distribute to meet the expected requirements of the application?
* What type of throughput should I expect as a function of the number of nodes deployed and the radio interface chosen (whether it be Bluetooth or Zigbee)?
* How is the Packet Error Rate of my Zigbee motes affected by the selection of adjacent frequency sub bands in the ISM 2.4GHz band?
* How is the localisation precision dependant on the number of nodes deployed in a corridor?

Communications and signal processing engineers, researchers and graduate students working in wireless sensor networks will find this book an invaluable practical guide to this important technology.

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 in microdrives.

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 MATLAB^® toolkits used to develop many of the results in this book can be downloaded from Professor Chen’s website.

Every physical actuator is subject to saturation.  When the actuator saturates, the performance of the control system designed will seriously deteriorate.  Currently there is a surge of interest in increasing the practical applicability of control theory by incorporating the effect of saturation into the design of a control system.

Control Systems with Actuator Saturation: Analysis and Design examines the problem of actuator saturation in depth.  The overall approach takes into account the saturation nonlinearities at the outset of the control design.  In the case that a control law is designed a priori to meet either the performance or stability requirement, it analyzes the closed-loop system under actuator saturation systematically and redesigns the controller in such a way that the preformance is retained while stability is improved.  It also presents some related results on systems with state saturation or sensor saturation.

Features and topics:

* Results apply to general open-loop systems, including exponentially unstable ones.  Thus, they are widely applicable to practical systems
* Problems such as controllability, stabilizability, transience performance, distribute rejection, and output regulation are treated in a systematic manner.
* Analytic description of the null controllable region is first obtained. Various feedback laws are designed that work on the entire null controllable region or an arbitrarily large portion of it.
* Analysis tools are developed for performance assessment of existing control systems under actuator saturation.
* Examples are worked out in detail to demonstrate the usefulness of the results.

This book is an excellent resource for professionals, researchers, practitioners and graduate students in control, electrical, and mechanical engineering.  All scientists and engineers interested in control systems with actuator saturation will find this book an essential resource.  Some first--year graduate courses in linear systems and multivariable control or some background in nonlinear control systems would greatly facilitate the reading of this book.

Exploring the design and use of micro- and meso-actuators, this book begins with theory and a general synopsis of the state-of-the-art in theoretical research. It discusses how to employ modern approaches in research and design activity, then presents a systematic list of already available products and details their potential for use. Design possibilities based on new technologies are clearly separated from those due to scale reduction, aiding in the selection of proper technology. The author takes a multi-physic approach to guarantee a comprehensive modeling technique, while the many references to experimental data and to existing microacutators assure an effective applicability of proposed theories..
