摘要
为了提高电励磁同步电机控制系统的可靠性,优化电励磁同步电机的调速性能,提出了一种带无速度传感器的电励磁同步电机模型预测电流控制策略。以模型预测电流控制作为电流环,取代传统的PI调节器,有效抑制电流纹波,提高了电流的跟踪性能。基于模型参考自适应理论,设计电励磁同步电机无速度传感器,对电机运行转速进行在线辨识,实现对转速准确估计。仿真结果表明:控制系统具有较好的快速性和可靠性。
In order to improve reliability of electric excitation synchronous motor control system and optimize its performance speed,a model predictive current control strategy for electric excitation synchronous motor speed sensorless. The model predictive current control is used as the current loop instead of the traditional PI regulator,which effectively suppresses the current ripple and improves the current tracking performance. Based on the model reference adaptive theory an electric excitation synchronous motor speed sensorless is designed to identify the running speed of the motor online,and realize accurate estimation of speed. The simulation results show that the control system is fast and reliable.
