自适应模糊自抗扰控制器的研究与设计

The design and research of fuzzy self-adapted ADRC arithmetic

针对普通PID在实际工程控制中参数整定难,抗干扰能力差的问题,设计了一种基于模糊控制原理的改进型自抗扰控制器。该控制器充分结合了模糊控制器和自抗扰控制器的各自优势,并对其进行了随动系统的仿真。仿真结果表明,该控制器可设计成为一个响应速度快、静差小的控制系统,与经典PID控制器在同样的系统中比较,自适应模糊自抗扰控制有较好的控制性能。

Because, in the stabilizing circuits, the common PID arithmetic is difficult to adjust this PID parameters and weak antijamming, a self- adapted active disturbance rejection controller （ADRC） with fuzzy control theory is designed. This controller has the advantage between PID and Fuzzy controller, And the results show that the Fuzzy- Self- adapted PID controller is better than PID controller.
