摘要
在控制永磁同步电机时,电流环的控制是实现伺服驱动系统控制的重要环节。为此,本文提出了一种基于无差拍算法的电机电流预测控制算法,以期改进电机电流环的性能。具体来讲,就是利用电流控制器计算电压矢量,然后通过调制模块将电压矢量转换为开关信号。在这一过程中,还要引进鲁棒电流预测算法,从而减小预测模型参数误差对系统的影响。经过仿真验证,这一算法的应用可以使系统电流环的稳态精度和动态性能得到提高。

For this purpose, a new predictive control algorithm based on the error free beat algorithm is proposed in order to improve the performance of the motor current ioop. ln particular, the voltage vector is calculated by the current controller and the voltage vector is converted to a switching signal by the modulation module, ln this process, the robust current prediction algorithm is also introduced, which can reduce the influence simulation results show that the application of of the parameters of the prediction model on the system. The this algorithm can improve the performance of the system.
