Robust Model Predictive Current Control for PMSM Control System

To enhance the robustness of conventional model predictive current control (MPCC) for PMSM drive, a robust MPCC is put forward. Because the motor parameters have a great influence on its control system, the sensitivity analysis of these parameters is carried out. Then, according to the parameter error and predictive current error model, the parameter error is calculated and compensated to the predictive model. Experimental results prove that the proposed method enhance the robustness of the system and erase the negative impact of parameter mismatch ultimately.
