一种基于自适应控制器的水流调节方法

PID控制器在自动控制系统领域有广泛的应用.针对活体鱼水质监测实验中复杂多变的水样环境,提出了一种适用于活体鱼水质监测实验的PID水流调节方法.该方法利用霍尔元件进行流量探测,将获得的流速数据与活体鱼适应的流速参考值相比较,通过自适应PID控制器计算出水流流速控制量.在保证控制精度和控制速度的前提下,适应复杂非线性的水样环境,实现实时动态水流调节.

A Water Flow Control Approach Based on Adaptive PID Controller

PID controller are widely used in automatic control systems.For the water sample,in the experiment of Live-fish water quality monitoring,is changeable and unstable,this paper designs a water flow control method based on adaptive PID controller.In this method,the Hall element for water flow detection,water flow value will be compared with the reference value,an adaptive PID controller calculates the control amount of water flow.For the premise of control precision and control speed,this method adapts to the complex non-linear water sample environment and achieves real-time dynamic water control.
