摘　　要：论文基于三套三相绕组构成的九相感应电机的数学模型,通过坐标变换,将其转换到以同步速旋转的三套互相解耦的等效绕组,把静止坐标系下的数学模型转换成正交坐标系下的动态数学模型。按照转子磁链定向的矢量控制原则,在给定磁链的条件下,在Matlab/Simulink中搭建了九相感应电机的矢量控制模型,仿真分析结果表明基于磁链开环电流闭环的矢量控制系统在稳态时转矩和转速波动小,并且在启动和加载过程中对电流和转速的跟踪速度快,系统具有很好的动静态响应。Based on the mathematical model of the nine phase induction motor consisting of three sets of three-phase wind⁃ings,this paper converts it to three sets of decoupled equivalent windings which rotate at the synchronous speed by coordinate trans⁃formation,and converts the mathematical model in the stationary coordinate system to the dynamic mathematical model in the or⁃thogonal coordinate system.According to the vector control principle of rotor flux orientation,a vector control model of nine phase in⁃duction motor is built in the condition of a given magnetic chain.The simulation analysis shows that the torque and speed fluctuation of the vector control system based on the flux linkage open-loop current and speed closed-loop is small in the steady state,and the current in the process of starting and loading is in the process of Matlab/Simulink.The speed of tracking is fast,and the system has good dynamic and static response.
