Abstract :

The paper presents a novel fuzzy logic controller for closed loop Volts/Hz induction motor drive system. Basically, in this paper the motor drive system comprises a voltage source inverter–fed induction motor (VSIM): namely a three–phase voltage source inverter and the induction motor. The squirrel–cage induction motor voltage equations are based on an orthogonal d–q reference rotating frame where the coordinates rotate with the controlled source frequency. Fuzzy logic is a part of artificial intelligence(AI), which is an important anch of computer science or computer engineering. The inputs to the fuzzy logic controller are the linguistic variables of speed error and change of speed error, while the output is change in switching control frequency of the voltage source inverter. In this paper a comparison between fuzzy logic controller and traditional PI controllers are presented. The results validate the robustness and effectiveness of the proposed fuzzy logic controller for high performance of induction motor drive. Simulink software that comes along with MATLAB was used to simulate the proposed model.
