Embedded based DC motor speed control system (Design, development)

The book deals with the design and developmental aspects of an embedded based system for DC motor speed control. The first speed-controlled drive was introduced by Harry Ward Leonard and it requires three machines for scheme implementation. After the invention of transistor and rapid development of electronics, new possibilities for accurate control of DC motor. The DC motor has been used widely in industry and the PID logic is applied to control motor speed, due to its excellent speed control characteristics. The PID family controllers are successfully applied to many practical process control applications involving the physical parameters like liquid level, liquid flow, pressure, temperature, rotational speed of motor etc. The methodology encompasses the design of PID controllers for DC motor controlling with step response and provides the means for a systematic adjustment of the controller gain in order to meet transient performance specifications. The present book describes the development of an embedded system which can be used in the on-line tuning of industrial PID controllers.
