模糊PID控制水位系统分析

PID调节规律对建立精确数学模型控制系统是非常有效的。但对于那些具有非线性、时变不确定性的控制对象,应用传统的PID调节器就难以实现有效的控制。文中提出了利用模糊PID控制技术,对水位进行控制,以使PLC对不同模型参数的系统均具有较好的控制性能,实现对系统动静态参数的最优控制。

Analysis of Indistinct PID Controlling Water Level System

PID regulating law is very effective for establishing a precise mathematical model control system.However,for those control objects with non-linearity,time-varying uncertainty,applying the traditional PID regulator would be difficult to achieve effective control.This paper proposed tocontrol the water level by using indistinct PID control technology,so that the PLC has better control performance on the system of different model parameters,to achieve optimal control of static and dynamic parameters of the system.
