Optimized Vector Control Strategy for Dual-Rotor Axial Flux Permanent Magnet Synchronous Motor for in-Wheel Electric Drive Applications

This paper analyzes the performance of dual-rotor axial flux permanent magnet synchronous motor for its application in electric motor drive. Dual-rotor single-stator topology is employed for analysis due to its superior features compared to other topologies of the motor for electric drive application. Constant torque angle control strategy with hysteresis current controller for inverter switching is implemented with the axial flux motor and is analyzed for validation. To enhance the robustness of the control strategy, the coefficients of proportional-integral controller are optimized with particle swarm optimization algorithm using Matlab/Simulink software to minimize the torque and speed ripples obtained from the conventional setting of proportional-integral controller. The performance analysis of the motor drive with optimized controller coefficients is carried out using Ansys co-simulation with Maxwell and Simplorer softwares. The simulation analysis of the motor with optimized constant torque angle strategy shows good motor performance and robustness which is inferred from results.
