摘要
本文在传统PID控制技术和模糊控制技术的基础上,吸收两者长处,设计了自适应模糊-PID控制器,并将其应用于压力控制中。基于S7-200PLC的自适应模糊-PID压力控制系统,以偏差和偏差变化率作为输入,根据被控系统不同工况变化的要求,通过修改PID控制器的参数来获得满意的动态和静态控制性能。
The self-adaptive Fuzzy-PID controller is designed based on traditional PID control technology and fuzzy control technology and it is applied to pressure control system. A self-adaptive Fuzzy-PID control system based on S7-200 PLC is carried out. It takes the deviation and the deviation change as input, according to varying performance state varying the parameters of PID controller to get good dynamic and static control quality.
