| 摘 要： | 通过对电流限定轨迹、转速限定轨迹和负载角限定轨迹的介绍,阐述了电动汽车用埋入式永磁同步电机的弱磁控制过程,有效拓宽了永磁同步电机直接转矩控制系统的调速范围.由于永磁同步电机弱磁是通过电枢反应达到弱磁运行目的的,电枢反应对永磁同步电机的参数有着重要的影响,并且弱磁程度越高,电枢反应越大.因此考虑了永磁同步电机的电枢反应对于电机转子磁链和交直轴电感等参数的影响,对比了不考虑电枢反应时各控制轨迹及弱磁性能.通过MATLAB/SIMULINK实现了考虑电枢反应和不考虑电枢的永磁同步电机直接转矩控制的弱磁控制.仿真结果验证了理论分析的正确性.

| Abstract: | Flux-weakening control of interior permanent magnet synchronous motor(PMSM) is elaborated by the presentation of current limit trajectory,speed limit trajectory and load angel limit trajectory.Flux-weakening control extends the timing range of the machine.For PMSM,flux-weakening is realized by armature reaction.In flux-weakening range,armature reaction will seriously affect the parameters of PMSM such as rotor flux,direct axis inductance and quadrature axis inductance.The control trajectories mentioned above and flux-weakening control performance of with and without considering armature reaction are compared using MATLAB/SIMULINK.The rationality of theory analysis has been proved by simulation results. |
