| 摘 要： | 为提高PMSM的电流控制精度，提出了一种优化的PMSM模型预测控制成本函数调整方法。基于传统成本函数引入定子电流幅值限制项以及开关状态限制项，对dq轴电流的控制进行优化，提高PMSM驱动系统电流控制的稳定性和精确性。仿真结果表明，所提方法相较于传统预测电流控制算法提高了电流控制精度，具备更快的动态响应速度和更强的抗负载扰动能力。

| Abstract: | Aiming at improving the current control accuracy of PMSM,an optimized cost function adjustment algorithm of model predictive control for permanent magnet synchronous motor was proposed in this paper.The limit terms of the stator current amplitude as well as switch state were incorporated into the conventional cost function so as to optimize the control of dq axis as well as improving the stability and accuracy of current control in PMSM drive system.The simulation results demonstrates that the proposed method compared with traditional predictive current control algorithm can improve the current control accuracy,and has faster dynamic response speed and better ability to resist load disturbance. |
