一种新颖的感应电动机控制仿真研究

Novel Control Simulation Research of Induction Motor

矢量控制是基于旋转坐标实现感应电动机的交、直轴电流的解耦控制,状态变换需要计算转子转差或转子磁链角的位置。提出了一种新颖的感应电动机解耦控制方案,该设计方法可以实现快速的转速、转矩和磁链的跟踪。与传统控制方法相比,该方法避免了转子转差或转子磁链角位置的计算。仿真结果证明了该设计方法的有效性。

Vector control realizes quadrature and direct axes decoupling of induction motor based on rotating coordinate. State variable transformation need the computation of rotor slip or rotor flux linkage angle. A novel decoupling control scheme of induction motor was given, which can realize fast speed, torque and flux linkage tracking. Compared with traditional method, the scheme avoids computation of rotor slip or rotor flux linkage angle. Simulation results prove the efficiency of the scheme.
