Automatic Disturbances Rejection Control-Based Model Predictive Torque Control for Permanent Magnet Synchronous Motor with Three-Phase Four-Switch Inverter
Authors: , , ,
Abstract: A novel automatic disturbances rejection control (ADRC)-based Model predictive torque control (MPTC) strategy is developed for permanent magnet synchronous motor (PMSM) with three-phase four-switch inverter. The dynamic model of PMSM with three-phase four-switch inverter is built. The ADRC and MPTC are respectively designed, the former being used to realize disturbance estimation and disturbance compensation while the latter being used to reduce torque and flux ripples. The resultant ADRC-based MPTC PMSM with unhealthy inverter, on the one hand, has fault-tolerant effective and has almost as dynamical performance as ADRC-based MPTC PMSM with healthy inverter, and on the other hand, compared with PI-based MPTC PMSM with unhealthy inverter, it possesses better command-following characteristics and disturbance rejection characteristics in the presence of variations of reference speed and load torque and its total harmonic distortion can be decreased. The simulation results validate the feasibility and effectiveness of the proposed scheme.
