The book presents a comprehensive treatment of the analysis and design of discrete-time control systems. It is written for courses on discrete-time control systems or digital control systems for senior undergraduate and postgraduate level engineering students. The text is presented in such a way that the reader can follow the discussions easily. The most significant feature of this edition of book is a greatly expanded treatment of the pole-placement design with minimum-order observer by means of the state-space approach and the polynomial equations approach. All materials necessary for understanding the subject matter presented (such as proofs of theorems and steps for deriving important equations for pole placement and observer design) are included to ease understanding of the subject. The prerequisites for the reader are a course on introductory control systems, a course on ordinary differential equations. Table of Contents Preface 1.

Katsuhiko Ogata is a professor of engineering who was born in Tokyo , Japan ; on January 6 of 1925 . He earned a Bachelor degree in Mechanical Engineering from the University of Tokyo in 1947. After receiving his degree, he spent three years as a research assistant at the Scientific Research Institute in Tokyo , followed by two years of industrial experience in Nippon Steel Tube Company, Japan. In 1952 he received a scholarship "Fulbright Travel Grant" to go to the United States and more advanced degrees. He earned a master's degree in Mechanical Engineering from the University of Illinois in 1953, and a Ph.D. in Engineering Science from the University of California , Berkeley in 1956.
Shortly after receiving his doctorate in 1956, he joined the Faculty of Mechanical Engineering at the University of Minnesota to teach and do research in the field of control systems. While he maintains his tenure at the University of Minnesota, also taught control systems in the Department of Electrical Engineering, Yokohama National University , Japan, for a total of three years.
K. Ogata, has authored seven textbooks, three of which have been published in various editions. His philosophy of writing has been that university engineering students should not spend too much time in deriving or verifying mathematical equations in control engineering. So in his books includes all leads and necessary for the student to understand the material from books without problems with math tests. This approach was well accepted by the control community worldwide. As a result, most of his books were translated into other languages, including Spanish, Portuguese, Japanese, Polish, Korean, Chinese, Malay. To date, 20 foreign editions of his books have been published. [ citation needed ]
While college counselor was about twenty years ago, its clear and thorough advice has earned him an award for Outstanding Advisor of the University of Minnesota.
It belongs to ASME , a member of Sigma Xi and Pi Tau Sigma . His biography is listed in Marquis Who's Who in the World, Marquis Who's Who in America, among others. [ citation needed ]
In 1999 won the "John R. Ragazzini Education" Award for distinction, because for a period of thirty years he has written textbooks on dynamics and control systems are widely recognized, especially, "Modern Control Engineering".
His most significant books ranging from "System Dynamics", "Modern Control Engineering", "Control Systems in Discrete Time", "Problems of Control Engineering using Matlab" to "Children's Literature, Briefly".
its gives insight regarding constrol system in discrete domain, although almost all of the control system now getting closer to continous time, it is still relevant information to improve the machine performance
