Torque Ripple Reduction and Speed Control of PMSM Using Fuzzy Logic for Propulsion Application

Permanent magnet synchronous machines are utilized for several applications in electric vehicles, industries,aerospace, domestic appliances due to highly efficient nature. The foremost problem thatmarks the working of PMSMs is torque and speedripples. Voltage feedback field weakening control is the prevalentmethod to diminish ripples as it is robust and simple since it won’talter in agreement with machine parameters. In this paper for fast speed dynamics and fewer ripples fuzzy controller is used and system has been developed using a PI and fuzzy logic controller. The results are analysed and an FFT analysis has also been donein MATLAB/Simulink.
