摘要：
The operating performance of permanent magnet synchronous motor current control strategy depends heavily on the motor parameters. The parameters of the permanent magnet synchronous motor will change due to the factors such as temperature rise and magnetic saturation. If the predictive current control is performed with the mismatched motor parameters, the current prediction value will be inaccurate and the optimal vector will be misjudged, resulting in the degradation of system control performance. In this paper, the performance degradation of the control strategy caused by the change of motor parameters is studied. The error models of delay compensation, current prediction, and vector dwell time are established respectively. The source and the transmission relationship of each link error are analyzed. On this basis, the three-vector model predictive current control strategy for permanent magnet synchronous motor drives with parameter error compensation is proposed. Taking a 6kW permanent magnet synchronous motor as the control object, the experimental results verify the feasibility and effectiveness of the proposed strategy. © 2020, Electrical Technology Press Co.
