Performance Improvement and Speed Control Of PMSM and IM for Water Pumping Applications

In this paper a PVA fed Induction machine (IM) and PMSM inverter drive circuit is proposed with vector control to maintain speed of the motor with respect to solar irradiation. The speed of the IM &PMSM is controlled by feedback from the sensor of machine. The speed controller is upgraded with MPPT reference speed estimation which generates required speed with respect to voltage and current feedback from PVA.The speed controller of PMSM is updated with 49 rule based fuzzy interface system with 7 membership functions. The circuit is modelled in MATLAB Simulink environment with results and graphs generated with respect to time.
