Performance and Comparison Analysis of Speed Control of Induction Motor using Improved Hybrid PID-Fuzzy Controller

It is difficult to control the speed of an induction motor. The speed control relies on the electric power factor offered to the motor. Many researchers have performed a significant number of studies to enhance the mechanism of vector control. They have used different controllers such as PI (Proportional Integral), PD (proportional derivative), Fuzzy-PI, Fuzzy PID (Proportional Integral derivative). In this paper, a novel approach is developed which used hybrid controller. This controller is developed by the amalgamation of Fuzzy type-2 and PID controller. Fuzzy type-2 has various advantages over type-1 fuzzy which overcome the limitations of the traditional system. A literature survey is given with the detailed information of the works done in this field. The mechanism is developed by taking into consideration different parameters such as rise time, settling time and overshoot. The proposed model is analysed using MATLAB. Simulation results showed the better efficiency of the novel controller. Is observed that, developed controller reduced the time required by the motor to achieve its target speed, thus, gives excellent outcome.
