機械控制工程基礎

Control Engineering has been recognized as one of the most important primary technology. It is significant to allow the technology to have much more influence in determining the discipline and body of knowledge to be incorporated in an undergraduate course. To meet the challenge in the 21st century,bilingual teaching becomes one of the most popular modes to train professionals who would be competent in the future. The teaching materials for the general technology has been carefully planned and compiled for the undergraduate students in accordance with the requirements of the obligated course and of bilingual teaching mode. There are 8 chapters in this book:Introduction to Control Systems,Building Appropriate Mathematical Models for a Control System,Time Response Analysis of Control Systems,Frequency Response Analysis of Control Systems,Stability Analysis of Control Systems,Steady-state Errors of Control Systems,Compensation Techniques,Digital Control. It covers the fundamentals of control engineering,including differential equations,transfer functions,signal flow graphs,time response,frequency response,s-plane,and state variable methods, fundamental theory of discrete control etc.. Drill Problems are appended to the end of each chapter for the students to practice. This book can be used as textbook or reading material for the course of controtheory as well as the course of English in automation. It also can be employed as reference for the teachers and students in the universities or in the colleges,technicians who major in mechanical engineering,control engineering or automation. ^[1]
