摘　　要：提出一种新的模糊控制方法,不但使串级系统的抗干扰能力增强,而且有效地解决了串级控制系统中主、副环时间常数的矛盾,对串级系统中滞后时间不确定的情况有较好的自适应性。与常规模糊控制不同的是把串级控制系统中的主、副对象作为模糊控制器的输入变量,并且在控制规则中引入了滞后因子,实验证实该方法具有广泛的应用价值。A new kind of fuzzy control method is presented. The method is provided with an improved antijamming technique and is especially capable of resolving the contradiction between the main ring and the accessory in a cascade system. The self-adaptability for the lag time of a cascade system is improved. It is distinguished from the conventional fuzzy control. Both main control and subcontrol serve as the input variables of the fuzzy controller, and the lag factor is induced to the control regulation, Experiments have shown that the method is of good aplication value.
