SIMULATION STUDIES ON HYBRID FUZZY-PI CONTROLLERS FOR DC MOTOR CONTROL

Abstract

DC motors are widely used in industry for their high reliability and low cost. It is desirable that the motor speed be controlled within a given specifications under various known or unknown disturbances. DC motors are extensively used in robotics, actuators and electrical equipment. Therefore, the control of the position or/and speed of a DC motor is an important issue and has been studied since the early decades in the last century. Extensive use of DC motors is due to their controllability of speed and their compatibility with the new digital system sets. Electric motors use a significant percentage of the electrical energy and even small improvement in operating efficiency could result in large reduction in consumption of energy. New techniques are therefore required to extract the ultimate performance from these motors/drives. In recent times, fuzzy control has emerged as one of the most attractive non linear controller for research and applications in the realm of indu...
