摘要
无刷直流电动机作为一个多变量强耦合非线性系统,采用经典PID控制难以得到满意的控制效果。采用自抗扰控制器来提高无刷直流电动机控制系统的动态性能和鲁棒性,自抗扰控制器设计过程中不需要对象模型结构和参数的精确信息。实验比较了PI控制器和自抗扰控制器的控制效果,结果表明自抗扰控制器(ADRC)对外部扰动和电动机参数的变化具有较强的鲁棒性。
For high coupling multi-variables non-linear brushless DC motor speed control system, it is difficult to achieve desired performance by using classic PID controller. Active disturbance rejection controller（ADRC）was proposed to improve dynamic performance and robustness of the brushless DC motor speed control system. For this method the plant model structure and exact parameter information is not requisite to the ADRC design process. The performance of PI and ADRC are compared, and experiment results show that ADRC has better dynamic performance and robust to external disturbance and internal motor parameter variation.
