Comparative Performance Analysis of PID and Fuzzy Logic Controllers for 150hp Three-Phase Induction Motor

Abstract

In this paper, comparative performance analysis of fuzzy logic controller and PID controller for space vector pulse width modulation (SVPWM)-based inverter-fed 150hp (horse power) three-phase induction motor which is used in the cable industry (Ravicab Cables Private Limited) at Bidadi is presented. In this cable industry, 611 Nm load torque is considered as full load and 305.5 Nm load torque is considered as half load for the three-phase induction motor. Proportional–integral–derivative (PID) controller-based voltage frequency drive (VFD) is used in this industry to control the speed of 150hp induction motor. Since VFD used in this industry is affected by several disturbances, robust speed controller is needed to be interfaced with the three-phase induction motor. In order to interface and identify the robust controller, this paper deals with simulation and comparison chart. As a part of the simulation, initially PID controller with real-time data which is used in this industry is interfaced with the 150hp induction motor under disturbance environment. Besides, the performance of this PID controller is analysed. Then, the proposed fuzzy logic controller is interfaced with the 150hp induction motor under disturbance environment. Moreover, the performance of this fuzzy logic controller is analysed. At the end, to identify the robust controller, the comparison chart is made.
