摘要
由于常规的直接转矩控制大多采用滞环比较器,容易产生转矩脉动,导致逆变器开关频率过高;与此同时,常规的PI速度调节器的跟踪精度不高。鉴于此,该文建立了电动车用永磁同步电机的数学模型,并利用MATLAB/ Simulink建立不仿真模型。设计了模糊直接转矩控制器和模糊速度PI控制器,并且借助实时仿真工具dSPACE,建立了永磁同步电机的实时仿真模型并进行仿真。仿真结果表明:所设计的电动车用永磁同步电机调速的双模糊控制器能自动调节开关频率,具有高的响应速度和很小的跟踪误差,为今后开发实际的硬件控制器打下了坚实基础。
Owing to conventional direct torque control mostly adopted stagnant ring comparator and as a consequence gave rise to the torque pulsating easily, and led to too high switching frequency. Meanwhile, the tracking accuracy of conventional PI speed control was not high enough. In view of this, paper built math model of PMSM used in EV and established simulation model by MATLAB/Simulink. Besides, designed the fuzzy DTC control and fuzzy P1 control to solve above problems and established the real-time simulation model of PMSM by dSPACE instrument. The simulation results presented that the double fuzzy control is more effective and robust than the conventional control and thus the foundation for further study and design of PMSM control hardware formed.
