| 摘 要： | 在永磁同步电机(PMSM)无速度传感器调速系统中,为解决负载扰动时控制性能变差的问题,提出用自抗扰控制技术的PMSM控制方案,将负载扰动归为未知扰动,用自抗扰控制(ADRC)来进行估计、补偿和控制.另外,为实现无速度传感器运行,利用ADRC中的扩张状态观测器(ESO)对扰动的估计值进行转速的辨识.仿真表明采用自抗扰控制方法不仅能够提高系统的响应速度,减小稳态误差,并且超调很小,能有效的抑制负载扰动带来的影响,而且ESO估计出来的转速精度高,对电机参数变化不敏感,鲁棒性好.

| Abstract: | A new control system of permanent magnetic synchronous motor(PMSM) which is made by the active disturbance rejection control(ADRC) is presented in this paper. The load disturbances are all contributed to unknown disturbance, and ADRC is used to estimate, compensate and control in the system. The speed is estimated by extend state observer(ESO) of ADRC. Simulation shows good performance of the system. |
