Modern Control Systems: An Introduction

Practitioner Tripathi explains the state-variable approach, which has several significant advantages over the transfer function, including direct time-domain elements suitable for digital computer computations, applicability to a range of systems, easier solutions and suitability for optimal performance projects. Tripathi's topics include the state-variable analysis of continuous-time systems, linear time-invariant and time-invariant analysis, eigenvalues and eigenvectors, analysis of discrete-time systems (with attention to the z-transform), stability analysis of nonlinear systems, optimal control and adaptive control, mathematical derivations and modeling, the Gilbert test, closed-loop systems, and Lyapunov's method. Includes answers to selected exercises and an appendix with a useful table on Laplace and z-transform pairs. This is designed as a text for a short course on control systems or as a self-study guide for professional engineers. Annotation c2008 Book News, Inc., Portland, OR (booknews.com)
