ANFIS based four quadrant chopper control of separately excited DC motor: A literature review

Abstract

Separately Excited DC motors (SEDCM) are widely used in industries because of their advantages in easy speed control and high performance. Their speed can be controlled by Armature voltage control and Field voltage control up to the base speed and above the base speed respectively. A rectifier or chopper is used as a converter to convert a fixed DC into variable DC to provide speed control to the motor. Many controllers have been applied for the control of motor speed. A closed loop control model has been developed having two control loops i.e. a speed control loop followed by a current control loop. Many researchers have proposed different models for this purpose. This paper presents a literature review of the research work done in this field till date. A comparative analysis is also done between the conventional methods and Artificial Neuro Fuzzy Inference System (ANFIS) based controller to find the best suitable method.
