摘要:
 摘要:针对感应电动机的电磁转矩表达式中转子电流与气隙磁通的强耦合问题,采用αβ0变换和MT0变换的混合坐标变换法,使得感应电动机的电磁转矩表达式解耦。推导了混合坐标变换,并给出了感应电动机混合坐标变换数学模型。在混合坐标系和ABC坐标系下分别建立了感应电动机的仿真模型,通过对比仿真结果,验证了感应电动机混合坐标变换数学模型的正确性。在混合坐标变换的应用中,以磁链开环、转速闭环的间接矢量控制仿真系统为例,仿真结果表明感应电动机的定子电流经过混合坐标变换解耦为产生磁场的定子电流分量和产生转矩的定子电流分量,验证了混合坐标变换的有效性。
Abstract:
 Abstract:For the strong coupling problem between the rotor current and the air gap flux in the expression of the electromagnetic torque expression of the induction motor, the hybrid coordinate transformation is adopted by the αβ0 transformation and the MT0 transformation, and the electromagnetic torque expression of the induction motor is decoupled. The hybrid coordinate transformation is deduced, and the mathematical model of hybrid coordinate transformation of induction motor is given. The simulation model of the induction motor is respectively established under the hybrid coordinate system and the ABC coordinate system. The mathematical model of the hybrid coordinate transformation in the induction motor is verified by comparing the simulation results. In the application of the hybrid coordinate transformation, the indirect vector control simulation system based on flux linkage openloop and speed closed loop is taken as an example. The simulation results show that the stator current of the induction motor is decoupled into the stator current component generating the magnetic field and the stator current component generating torque by the hybrid coordinate transformation, so the validity of the hybrid coordinate transformation is verified.
