Abstract
Among various drive systems, multiphase Permanent Magnet Synchronous Motor (PMSM) drives have attracted significant attention due to their inherent advantages associated with multiphase operation. This Study presents the modelling and simulation of a two-inverter-fed six-phase PMSM drive system. A comparative analysis between a conventional Proportional–Integral (PI) controller and a Fuzzy Logic Controller (FLC) is performed based on starting torque, settling time, and steady-state current under different speed and load conditions. The PI controller shows limitations such as longer settling time and slower dynamic response during sudden load variations. To overcome these issues, a fuzzy logic-based intelligent controller is implemented and tested in the MATLAB/Simulink environment under no-load, constant load, and dynamic load conditions. Simulation results demonstrate that the fuzzy controller provides faster response, higher starting torque, improved robustness, and better performance compared with the conventional PI controller.
