摘要：The Permanent Magnet Synchronous motor is a rotating electrical machine where the stator produces a sinusoidal flux density distribution in the air gap and the rotor has permanent magnets. A substantial air gap magnetic flux generated by permanent magnet makes it reliable to design highly efficient motors. However, the main disadvantage is the non-uniform variance in the developed torque. These torque ripples causes speed oscillations and vibrations and perverts the system performance. Since the construction of permanent magnet synchronous motor lacks rotor coil which will provide mechanical damping during transient conditions, these motors are inefficient with open-loop V/Hz control and rely on Vector Control for better dynamic response. Fuzzy logic controllers which does not requires any modeling of a system based on mathematics and are they are working on the linguistic rules. It also improves the performance of PI controllers which are affected by load turbulence, parameter variations and speed disturbances. This project presents the Fuzzy logic approach for a vector controlled PMSM drive for minimizing torque ripples. Also, Space vector modulation is employed to overcome the periodic torque pulsations generated by hysteresis controllers. The design analysis and the hardware control are implemented by using FPGA controller and discussions on the hardware results are done.
