摘要
基于永磁同步电机的数学模型,以转子磁场定向id=0控制和空间矢量脉宽调制相结合的方法进行控制。针对速度伺服,采用改进型指数趋近率滑模变结构控制,在Matlab/Simulink环境中进行了建模与仿真。仿真结果表明与一般指数趋近率滑模控制相比,改进型指数趋近率滑模变结构控制器控制永磁同步电机,超调量小、速度响应快、抖振小、对各种外界干扰也得到了很好的抑制。最后,在TMS320F2812DSP开发板硬件实验平台上,对永磁同步电机的速度控制进行了实验验证。
Based on the mathematical model of permanent magnet synchronous motor, rotor flux oriented vector control id = 0 and the phase space vector pulse width modulation were introduced. Improvement exponential approach law sliding mode for speed servo system were modeled in the Matlab/Simulink software. The simulation illustrates that improvement exponential approach law sliding mode variable structure control- ler makes PMSM less overshoot, quick velocity response less chattering and has good depression of many disturbances than traditional exponential approach law. Finally, a TMS320F2812 digital signal processor （DSP） was used to set a control system of PMSM which was verified in this paper.
