一种混合PID控制器的设计

The Design of a Kind of Hybrid PID Controller

传统PID方法的控制参数难以精确整定,故其控制精度也难以得到保证。本文提出了一种混合PID控制器的设计方法,它是采用神经网络作为补偿器,与传统PID一起来对被控对象进行综合控制。仿真研究结果表明该方法较传统PID有更好的控制效果。

It is difficult to get the precise parameters of traditional PID controller, thus the accuracy of its control is not insured. In this paper, a kind of hybrid PID controllers design method is presented. It uses neural network to compensate the traditional PID controller, and the plant is controlled together. The results of simulation show that the method can yield better control effect than the traditional PID controller.
