"Control System Design Guide, 3E" will help engineers to apply control theory to practical systems using their PC. This book provides an intuitive approach to controls, avoiding unnecessary mathematics and emphasizing key concepts with more than a dozen control system models. Whether readers are just starting to use controllers or have years of experience, this book will help them improve their machines and processes. The key features includes: key topics are demonstrated with realistic models of control systems; all models written in Visual ModelQ, a full graphical simulation environment available freely via the internet; and, new material on OBSERVERS explained using practical applications. It explains how to model machines and processes, including how to measure working equipment; describes many nonlinear behaviours seen in industrial control systems. It covers electronic motion control, including details of how motors and motor feedback devices work, causes and cures of mechanical resonance, and how position loops work.
