摘要
对于较大容积容器的压力精确控制中,通用压力控制器存在着气路管径小、调节时间长的问题,提出了充放气分别采用双管路多分级的气路形式和Fuzzy-PID的控制方法,并给出了Fuzzy-PID控制器的设计模型。通过实验与采用单管路方式的气路设计作对比,验证了针对较大容积容器而设计的压力控制器具有较快的响应速度和较高的控制精度。
Aimed at the problem that in normal air pressure controllers air channel＇s caliber is so small that it takes a long time to regulate the pressure in pressure control of large container. Separated double-air channels with several grades air channels in air inflation and air deflation and the fuzzy-PID control method is adopted. Design model of fuzzy-PID controller is presented in detail. Fast response and high control precision are confirmed by comparison with the design of single-air channel in experiments.
