PID Control

This book describes how to control variables of physical dynamic systems-level, temperature, pressure, speed, and position-using PID controllers (implementing proportional + integral + derivative control action). The PID control function is without a doubt the most important and most frequently used control function in practical industrial applications. There may be hundreds of PID control systems in one industrial plant to keep process variables close to their set-points and to ensure the stability of the whole plant. The book gives a well written and easily understandable introduction to practical and theoretical aspects of PID control of dynamic systems. It is well suited for introductory control courses and also serves as a reference for the practical engineer.
