摘要
在交直流调速和自动控制原理的基础上,针对异步电机矢量控制5个环节中的电流控制环节,从理论上分析研究了PI调节器、前馈解耦、滑模控制3种电流控制器解耦算法的优缺点,并通过搭建实验仿真平台进行仿真,得到了3种电流控制器的数据及其波形,综合理论分析对比了3种算法的特点,为矢量控制时电流控制器的选择提供了参考。
Based on AC/DC speed regulation and automatic control principle,three kinds of current controllers,namely PI regulator,feed forward decoupling and sliding mode controller,are theoretically analyzed for the current control links in the five stages of asynchronous motor vector control.The advantages and disadvantages of the decoupling algorithm,and the simulation of the experimental simulation platform,the data of three kinds of current controllers and their waveforms are obtained.The characteristics of the three algorithms are compared by comprehensive theoretical analysis,which provides references for the selection of current controller in vector control.
