Fuzzy control of integrated current controlled converter-inverter fed cage induction motor drive

The paper presents the performance analysis of a vector controlled cage induction motor drive. The drive is fed from a current controlled converter-inverter system. The switching technique being used in the control of the converter as well as inverter is PWM current control. Closed loop control of the cage induction motor utilizes the fuzzy PID speed controller. Advantages offered by the current control converter-inverter link are exploited. In order to examine the dynamic performance of the drive system its model is simulated and results are analyzed. The potential applications of this particular drive system are outlined
