Feedback Control Systems, 5/eThis 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-helps students understand the difference between mathematical models and the physical systems that the models represent.
Professor John M. Parr received his Bachelor of Science degree in Electrical Engineering from Auburn University in 1969, an MSEE from the Naval Postgraduate School in 1974, and a PhD in Electrical Engineering from Auburn University in 1988. A retired U.S. Navy Officer, he served as a Program Manager/Project Engineer at Naval Electronic Systems Command in Washington, DC and Officer in Charge - Naval Ammunition Production Engineering Center, Crane, Indiana in addition to sea duty in five ships. Dr. Parr participated in research related to the Space Defense Initiative at Auburn University before joining the faculty at the University of Evansville. Dr. Parr is a co-author of another successful Electrical Engineering textbook, Signals, System and Transforms, by Phillips, Parr and Riskin. He is a registered professional engineer in Indiana, and is a member of the scientific research society Sigma Xi, the American Society of Engineering Educators (ASEE), and a Senior Member of the Institute of Electrical and Electronic Engineers (IEEE)
