Self-Tuning Fuzzy–Pi Controller in Volts/Hz Induction Motor Control For Electrically Driven Ship Propeller
Journal Title: Academic Research International - Year 2014, Vol 5, Issue 5
Abstract
The induction motors are widely used in industrial applications, especially in electric propulsion system. Induction motor is required to rotate the propeller for producing ship propulsion. The volt/Hz (V/f) control based induction motor (IM) using conventional PI controller with fixed parameters cannot provide desired control performance under load disturbance and transient conditions. In this paper, Fuzzy-PI controller is proposed and presented to improve the dynamic performance of the IM drive. Fuzzy logic (FL) is used to adjust the parameters of PI controller according to various systems operating condition. The effectiveness of the proposed systems is verified by simulation process. Therefore, the Fuzzy-PI controller has better performance compared to the conventional PI controller during change of operating condition. Simulation results of Fuzzy-PI controller show that the induction motor rapidly reaches the speed reference, has small steady state error and overshoot. And also reduce speed oscillation during load disturbance condition.
