针对永磁同步电机存在的非线性、强耦合、参数摄动等问题,设计并实现了基于自抗扰控制器(ADRC)的矢量控制系统。首先提出基于ADRC的控制策略,实时观测出由系统内部非线性因素以及外部扰动引起的“内外扰动”并进行补偿,从而实现精确控制;其次研制基于DSP的多轴运动控制卡,并在此基础上实现了基于ADRC的PMSM矢量控制系统。仿真及实验结果表明,系统具有良好的动态性能及鲁棒性,能够快速加工出符合要求的模型。
The permanent magnet synchronous machine (PMSM) is a nonlinear multi variable coupled system. This paper pro- posed a vector control system based on the auto disturbance rejection controller(ADRC ). Firstly, a strategy based on ADRC is pro- posed to estimated and compensated the disturbances. Second, a DSP-based multi-axis motion control card is designed. Simulation and experimental results show that the vector control system is simple, and will improve the stability, robustness and adaptability in the system significantly.
