工业锅炉汽包水位先进PID控制研究

锅炉是工业生产中重要的动力设备,在实际运行过程中,基于安全性、稳定性及经济性等方面的考虑,汽包水位须维持在某一期望值附近.以MATLAB为仿真平台,构建汽包水位三冲量控制系统,分别采用常规PID控制器、模糊自适应PID控制器和基于遗传算法的PID控制器.常规PID控制器参数是由人工整定且固定不变的,其控制效果存在进一步提高的空间.模糊自适应PID控制算法能在线整定、优化PID参数,遗传算法能根据模型自动寻找最优PID参数,汽包水位控制系统中常用的先进控制算法.通过比较仿真结果.发现使用先进PID控制算法能有效地加快响应速度、减小超调量、减少调节时间、提高克服扰动的能力.

Advanced PID Control of Industrial Boiler's Drum Water Level

Boiler is a necessary power equipment in the industrial production.In order to ensure the security,stabilization and economy of the boiler in a process,the drum level should be controlled close to a desired value.A three-impulse PID control system of drum level is built with MATLAB,and traditional PID controller,fuzzy adapted PID controller,PID controller based on generic algorithm are then taken in use.However,the parameter of traditional PID controller is tuned by human,which can't be changed any more,so ...
