Dead-beat Predictive Current Control for Permanent-Magnet Synchronous Motor Drives Considering Parameter Mismatch

To enhanced the parameter robustness of the conventional dead-beat predictive current control (DPCC) approach, this paper presented a DPCC considering parameter mismatch (DPCC-CPM) approach for the permanent magnet synchronous motor (PMSM) drive system. Firstly, an extended reference voltage model considering the compensation of parameter mismatch is established and the compensated result is calculated in real time by a newly designed cost function. Then, the reference voltage is acquired accurately and is modulated using space vector pulse width modulation (SVPWM). Finally, the simulation results demonstrate that the presented DPCC-CPM approach can effectively compensate for the undesirable influences due to parameter mismatch, providing satisfactory control performance.
