This comparative analysis evaluates modulated model predictive control performance in low-inductance PMSM drives, highlighting key advancements and performance metrics.
Model predictive control (MPC) is one of the advanced control strategies implemented for different applications to provide better performance and faster dynamic response. Modulated model predictive control (M2PC) is one of the recent MPC structures. It is developed based on the fixed switching frequency modulator and duty cycles concept, resulting in improved performance indicators under different operating conditions. In addition, one of the given PWM topologies that gained much attention due to higher switching frequency operation with similar power losses is discontinuous pulse width modulation (DPWM). Therefore, different M2PC methods including deadbeat control (DBC-M2PC) and cost function ratio (CFR-M2PC) have been implemented for low-inductance high-speed permanent magnet synchronous motor (PMSM) drives employing DPWM. The DBC-M2PC strategy shows a superior performance over the CFR-M2PC approach. Simulation analysis along with practical investigation through a dedicated high-speed testing rig are illustrated for both methods.
