对传统模糊控制的双重特性进行了深入探讨．定性和定量分析都显示出模糊控制 集中了相对应的线性控制和变结构滑模控制的特性．该双重特性可以通过改变属性函数和增 益来调整．高的增益和多个属性函数会导致强的变结构控制和弱的线性控制，反之亦然．仿 真结果证实了以上分析．困变结构控制更多地用于较复杂过程，而线性控制则用于较简单过 程，故独特的双重特性对模糊控制的设计和调整影响重大．对于简单过程，模糊控制的初始 增益可以用已调好的线性控制参数来设计；对于复杂过程，可用变结构控制理论来设计．模 糊控制的双重特性有助于解释其对复杂过程有较佳的鲁棒性．
The dual characteristics of traditional fuzzy control are discussed in depth. Both qualitative and quantitative analysis show that fuzzy control concentrates on the corresponding characteristics of linear control and variable structure sliding mode control. This dual property can be adjusted by changing the property function and gain. High gain and multiple attribute functions result in strong variable structure control and weak linear control, and vice versa. The simulation results confirm the above analysis. Dilemma structure control is more used for more complex processes, and linear control is used for simpler process, so the unique dual characteristics of fuzzy control design and adjustment of great impact. For the simple process, the initial gain of fuzzy control can be designed with the linear control parameters adjusted well. For complex processes, the variable structure control theory can be used to design. The dual nature of fuzzy control helps to explain its robustness to complex processes.
