循环流化床锅炉炉膛负压模糊自适应PID控制

模糊参数自适应PID控制器将模糊控制技术的原理和常规数字PID控制算法相结合,实现数字PID控制器的参数在线动态自调整。在大型循环流化床锅炉试验台上组成负压控制系统对该控制算法进行实现。运行结果表明：相对于常规PID控制器,该控制器能减少系统调节时间60％以上,减少系统最大超调量10％以上,应用于循环流化床锅炉炉膛负压控制系统中能取得良好的控制品质。

Fuzzy-PID Controller Used in Negative-press Control System of CFBB

Parameter Self-Adapting fuzzy-PID controller is the integration of fuzzy control technology and normal digital PID control technology,which carries out the digital PID controller＇s parameter online Self-Adapting.In order to test the effect of the arithmetic,this paper constructed a validating negative press of hearth control system based on small CFBB test-bed.As the result of the experimentation showed,compared with general PID controller,this controller can reduce the accommodation time over 60%,reduce maximum overshoot over 10%.
