Abstract
Model predictive current control of dual three-phase permanent magnet synchronous motor (PMSM) has become a research hotspot because of its intuitive concept, less controller parameters and easy to handle fault-tolerant control and nonlinear constraints. However, mismatched motor parameters lead to stator current prediction error. To solve this problem, a robust predictive current control with prediction error correction (PEC-RPCC) is proposed in this paper, where a correction term is added to stator current prediction equation. The correction term consists of the difference between the predicted value and the sampled value of the stator current in the previous step. Simulation results verify the effectiveness of the method.
