摘　　要：从内模控制的鲁棒机理入手,分析了内模控制的性能,其具有良好的抗扰性和鲁棒性。由于电机参数时变会影响矢量控制系统性能,提出具有高性能的新型异步电机变频调速内模控制系统结构,设计了内模控制电流调节器和速度调节器,解决了矢量控制系统参数鲁棒性差的问题,理论分析与实验证明了该方案的有效性。Starts with the robustness mechanism of internal model control（IMC）, the performance of the internal model control is analyzed, it has the good performance of anti-disturb and robustness. Because the influence of machine time-varying parameter on the performance of vector control system and presents a new highperformance induction motor frequency conversion regulating speed internal model control system. The current regulator and speed regulator based on IMC are designed. It can effectively solve the problem of the weak performance of parameter robustness in vector control system. The theories and the experiments demonstrate the validity of this project.
