This is the third edition of an introductory text, substantially updated to encompass revisions in technology since first publication. Its goal is stated as providing the necessary insight, knowledge and understanding required to analyse and design computer controlled systems effectively.
A broad outline of computer control is presented, with many examples and key points of theory. The analysis of discrete time systems is considered in detail with both state space and input-output models of systems in subsequent chapters allowing direct comparisons between the two. The real issues of load disturbance, feedforward and command signal following are introduced at an early stage before general design issues for larger systems, and the tools for dealing with aliasing problems. The development of approximations of analogue controllers and the practical implementation issues of digital controllers are discussed. The final four chapters concern the characterisation of disturbances, designing controllers in the light of this information and experimental methods to achieve this. Examples are provided with MATLAB and SIMULINK in mind, with files available through ftp, in addition to further educational resources from the authors' Web site.
The book is a classic textbook, ideal for student courses (its inspiration) as well as revision or updating for the control professional. Its coverage is broad, and includes plenty of practical asides and even C listings of software when illustrating algorithms, making it a useful reference.
