Study on Generalized Predictive Control for Permanent Magnet Synchronous Motors

对于永磁同步电动机 ,在对其数学模型进行详细分析的基础上 ,在转子坐标系中建立了永磁同步电动机传动系统SISO(单输入输出 )的CARIMA(受控自回归积分滑动平均 )模型 ,研究了同步电动机速度模态的广义预测控制的理论 ,通过仿真可以看出调整预测步数Ny,及控制加权序列λ 。

By analyzing the mathematical model of the permanent magnet synchronous motor (PMSM), a single input single output(SISO) and controlled auto-regressive integrated moving average(CARIMA) model of the PMSM drive system is established.And the generalized predictive control (GPC) approach for the PMSM is proposed.Simulation shows that the performance of the system.Can be improved by increasing the prediction horizon N f and the control weighting factor.
