The book represents a course reference for Universities and Engineering Schools offering courses on applied computer-controlled systems and system identification. In addition to its academic audience, Digital Control Systems is aimed at practising engineers wishing to acquire the concepts and techniques of system identification, control design and implementation using a digital computer. The industrial references for the techniques presented in the book and the various applications described provide useful information for those directly involved in the real-world uses of control. Readers who are already familiar with the basics of computer-controlled systems will find in this book a clear, application oriented, methodology for system identification and the design of various types of controllers for single-input, singleoutput (SISO) systems.
