I disagree with a former review which states this book is outdated. IMHO it is a well balanced treatment of "Digital Control Systems" (DCS) that explains the fundamental mathematics (Z-transform, linear difference equations), the fundamental control design techniques and figures of merit (Root Locus in the digital domain, transient response, static errors, stability, conversion of analog controllers/compensators via the bilinear transformation, impulse invariance and step invariance) as well as more advanced control techniques, such as state-variable feedback with observers and with full or partial state-feedback, and also has a chapter on linear optimal control.The last 4 chapters deal with stochastic control and estimation, starting by the fundamental concepts from probability theory and ending in the Kalman filter (optimal state estimator), the fundamentals of system identification, and the design of controllers in the presence of disturbances in the parameters or of measurement noise. Practical issues are also covered, such as AD and DA conversion and the effect of quantization errors.The treatment of digital control follows modern texts, so it is a still a good modern reference after 20 years since it was written. Most (if not all) explanations and mathematical derivations are complemented with small-size examples that help in the understanding of the matters. At about 400 pages, it is suitable for suitcase transport. It is a much nicer introduction to Digital Control than the books from Isermann (Digital Control Systems: Volume 1: Fundamentals, Deterministic Control and the companion vol. 2) and from Astrom and Wittenmark (Computer Controlled Systems: Theory and Design (Prentice-Hall information and system sciences series)), for example, although it is less thorough.Nonlinear control and adaptive control are not studied in this book. So, in conclusion, the book from R. Jacquot is perfectly suited for an upper-undergraduate or graduate course in "Digital Control", balancing quite nicely mathematics, control practice, algorithms for designing controllers and fundamental concepts. A very good book.
