摘要: 根据电阻炉温控制的特点,即只有升温单向控制、滞后较大且具有参数时变性,利用模糊推理合成法建立模糊模型并进行模糊控制器设计,为提高模糊控制的精度,引入模糊变量K,构成参数自调整模糊控制系统.该系统可根据误差和误差变化在线自动调整控制器参数,使系统的稳态精度得到改善.Abstract: According to the characterestic of resistance furnace temperature control,temperature rising oneway control,large time delay and timevariation of parameter,using method of fuzzy compositional rule of inference establish fuzzy model and design fuzzy cntroler.In order to increase control system precision,it gives a fuzzy variable K,and sets parameter selfadjusting fuzzy control system.This system can on line selfadjusting controller parameters according to the error and variations of the error.It makes the system steady precision improved.
