A Motor-Parameter-Free Model Predictive Voltage Control for PMSM Drives Based on Incremental Prediction Model

The traditional model predictive voltage control (T-MPVC) approach employed for permanent magnet synchronous motor (PMSM) has a strong parameter dependence. Therefore, with the intention to decrease the parameter sensitivity of PMSM, a motor-parameter-free model predictive voltage control approach is suggested in this paper. First, an incremental voltage expression is established to alleviate the impacts of flux-linkage and resistance parameters. Second, an integral controller is devised for obtaining the aggregate parameter information containing the inductance and incorporate it into the already established incremental voltage expression, thus implementing the motor-parameter-free model predictive voltage control. Then, the computational complexity is further reduced by utilizing the fast vector selection approach. Finally, the conclusions of the simulation demonstrate the validity of the suggested approach.
