Drawing on experience as, both, an engineer and a recognized best-selling author, the author introduces theory and applications of control systems through numerous examples. This wonderful treatise speaks of the author?s immense knowledge; vast experience in teaching courses pertaining to modeling of physical system, control systems, electronics, power electronics, motor control, and integration of computer simulation tools; and also work experience as an instrumentation and control engineer in a refinery, and research and development engineer of industrial motor control. Nowadays, the role of a control systems instructor has changed from explaining the theories through drawings, plots, and derivations to demonstrating the applications of the software tools that are based on the theories used to perform the analysis and design of control systems. This book emphasizes the importance of integrating computer software tools such as Mathcad for design verifications and evaluating system performances. For example, one can use Mathcad software to convert time domain functions to Laplace domain functions, and vice versa; solve partial fractions and time domain solutions directly; solve differential equations; and plot Bode and Nyquist diagrams. This textbook is designed for students pursuing BS/BE degree in engineering. The essential topics of control system are included in such a manner that they can be covered in a single semester of typically 14?15 weeks. A course on control systems is usually required in electrical, electronics, mechanical, and chemical engineering UG curriculum and often in graduate programs.
