摘　　要：该文归纳整理永磁同步电机交直轴电流解耦控制方法,分析各种解耦方法的思想来源、脉络体系和演变过程,论证不同解耦方法的解耦本质和内在联系。从整体和局部视角出发,建立解耦问题的思维架构,概括出对角化解耦、抗干扰解耦和逆系统解耦3类方法。3类方法依次体现出模型依赖性降低、鲁棒性增强、算法复杂度提高的趋势,呈现出从“模型论”向“控制论”过渡的技术发展路线。讨论参数不确定条件下各种解耦控制方法的鲁棒性,指出将解耦方法与先进控制算法、扰动观测技术、系统辨识方法以及人工智能方法相结合,并充分利用已知的模型信息,有利于提升交直轴电流解耦效果,增强系统鲁棒性,减弱单一观测器、控制器、滤波器等的设计难度与参数整定要求,有助于实现系统全局最优。最后,对永磁同步电机交直轴电流解耦问题的关键技术、应用与发展做出展望。This paper summarizes the control methods of dq axis current decoupling for permanent magnet synchronous motor(PMSM),analyzes the thought source,thread system and evolution process,and demonstrates the decoupling nature and internal relations of various decoupling methods.From a global and local perspective,this paper establishes a thinking framework about the decoupling problem.The decoupling methods are classified into three categories:diagonal decoupling,anti-interference decoupling and inverse dynamic decoupling,which reflects the trend of the reduced model dependence,robustness enhancement,and the complexity of algorithm,as well as shows the sign of the transition from model theory to cybernetics.This paper also discusses the robustness of various decoupling control methods under the condition of parameter uncertainty.It is pointed out that combining the decoupling method with advanced control algorithm,disturbance observation method,system identification method and artificial intelligence method,and making full use of known model information are beneficial to improving the effect of dq axis current decoupling,enhancing the robustness of the system,reducing the design difficulty and parameter tuning requirement of single observer,controller and filter,and even achieving the global optimum of the system.
