Self organising fuzzy controller for CSI fed induction motor

A self organising fuzzy controller is applied to the closed loop speed control system of an induction motor fed from an auto sequential current source inverter. The induction motor is controlled to operate in constant flux mode. The scaling factors of input to the controller and output are altered to modify the speed response. For obtaining better steady state response, nested control windows of a lookup table are used. The results show that the response with this controller is superior to the response with a PI controller especially when the motor is loaded or the load is altered.<
