摘　　要：为提高控制系统的动态性能和鲁棒性,设计了无刷直流电机自抗扰控制方案。自抗扰控制器利用其内部的扩张状态观测器估计系统的内外扰动,据此将电机等效为由两个非线性系统构成的串联对象,然后设计两个一阶自抗扰控制器实现对电机的内、外环控制,内环控制电流,外环控制转速。实验结果表明,自抗扰控制器对电机模型的不确定性和外部扰动变化具有较强的适应性和鲁棒性。控制系统具有优良的动态性能。In order to achieve high dynamic performance of control system, a new strategy for brushless DC motor is designed by using ADRC in this paper. Extended states observer （ESO） in ADRC can cal- culate the real-time value of disturbance, So the motor model is transformed into a series-connection ob- ject. The control design includes two one-order ADRCs. One ADRC controls the current in armature winding. Which is the inner loop. And the other ADRC controls rotor speed, which is the outer loop. The experiment results show that the controllers ensure very good robustness and adaptability under mod- eling uncertainty and external disturbance and produce better dynamic performance.
