Revised and edited for optimum clarity, the text helps readers understand the difference between mathematical models and the physical systems that the models represent. Revised and edited for optimum clarity, this reputable text offers a thorough analysis of the principles of classical and modern feedback control. Organizing topic coverage into three sections--linear analog control systems, linear digital control systems, and nonlinear analog control systems--it strives to help students understand the difference between mathematical models and the physical systems that the models represent. Key Benefit: Designed for self-study by practicing engineers with little or no experience in control systems, this reputable text offers a thorough analysis of the principles of classical and modern feedback control. Organizing topic coverage into three sections—linear analog control systems, linear digital control systems, and nonlinear analog control systems—it strives to help readers understand the difference between mathematical models and the physical systems that the models represent.Key Topics: Revised and edited for optimum clarity, the text develops both the transfer-function model and state-variable model for the analysis and design of linear analog systems, and discusses the important concept of system stability, along with the Routh-Hurwitz stability criterion. It explores modern control-system design, developing pole-placement design and introducing the design of state estimators, and includes coverage on such nonlinear system analysis methods as describing-function analysis, linearization, and the state-plane analysis. Introducing expanded frequency-response design criteria early in the presentation to help explain closed-loop systems, the text offers two Control Systems Programs (CPS) containing software and documentation for the IBM PC and compatible computers. New Third Edition features include a section on time-scaling differential equations to help users relate the transfer functions of systems examples to those of practical systems; plus additional practical applications—both as examples and end-of-chapter problems—to better relate the mathematical developments to physical systems.
