Robust Predictive Current Control for PMSM Drives with Parameter Mismatch

Classical direct predictive current control (PCC) method for permanent magnet synchronous motor (PMSM) needs to predict the future motor behavior according to its accurate model, the parameter mismatch will deteriorate the PCC scheme performance. To enhance the robustness to parameter mismatch, this paper propose a method to revise current prediction model within each sampling time according to the measured information. The modified current predictive equations consider influence of all electrical parameters. The simulation results compared to classical PCC method have verified the validity of proposed method.
