STUDY THE ABILITY OF REPLACING FUZZY AND PI CONTROLLERS WITH THE HEDGE - ALGEBRAS - BASED CONTROLLER FOR A DC MOTOR

Abstract

DC motor is an important control subject in a very wide range of applications for many different areas. With such, the PI Controller has been widely used by many authors in the world to control a DC motor. Fuzzy controller is also used to replace the PI controller to ensure appropriately flexibility in process control. However, system responses of the PI and fuzzy controllers have been settling times with high overshoots and non - zero steady-state errors. So, the paper addresses to study ability of replacing the PI controller and fuzzy controller with the hedge algebras - based controller for DC motor. The simulation results in comparison with the conventional controllers, demonstrate the effectiveness of the novel hedge algebras - based controller.
