PID模糊控制重要的任务是找出PID的三个参数 与误差e和误差变化率ec之间的模糊关系，在运行中不断检测e和ec，根据确定的模糊控制规则来对三个参数进行在线调整,满足不同e和ec时对三个参数的不同要求。(The important task of PID fuzzy control is to find out the fuzzy relation between the three parameters of PID and the error E and the error rate EC. In the operation, e and EC are constantly detected. According to the fuzzy control rules, the three parameters are adjusted online to meet the different requirements for the three parameters of the different E and EC.)
