Indirect Vector Controlled Induction Motor with four Hybrid P+Fuzzy PI Controllers

In this paper, a new high performance induction motor drive is presented. The induction motor is controlled with four proportional plus fuzzy PI controllers (P+FUZZY PI). This hybrid controller replaces the conventional PI controllers traditionally used for indirect vector control of induction motors. The hybrid indirect vector control using the fuzzy controllers offers enhanced performance both in mathematical simulations and during actual test utilizing a 7.5 kW induction motor. The results demonstrate the superior performance and robustness of the fuzzy logic controller over the conventional controller when there are mismatched motor parameters. Notably, the performance of the fuzzy logic controller is retained when a new different motor replaces the test motor.
