Feedback Control SystemsPrentice Hall, 2000 - 658 pages This self-study book offers optimum clarity and a thorough analysis of the principles of classical and modern feedback control. It emphasizes the difference between mathematical models and the physical systems that the models represent. The authors organize topic coverage into three sections--linear analog control systems, linear digital control systems, and nonlinear analog control systems, using the advanced features of MATLAB throughout the book. For practicing engineers with some experience in linear-system analysis, who want to learn about control systems. |
