以RM,RZ,R03个蕴涵算子为基础,给出了其相应三Ⅰ算法的表达式,并研究了这3个蕴涵算子基于三Ⅰ算法构成的单入单出模糊控制器,分析了它们的响应能力.结果表明,当Ri(i=1,2,3)按顺序取R0,RM,RZ时基于三Ⅰ算法构成的单入单出模糊控制器具有函数的泛逼近性;当Ri(i=1,2,3)按顺序分别取RM,RZ,RZ或R0,RZ,RM时基于三Ⅰ算法构成的单入单出模糊控制器近似为一元拟合函数;其余情况基于三Ⅰ算法构成的模糊控制器具有阶跃响应能力.
Expressions of triple I algorithm based on RM, Rz and R0 are shown. Accordingly, SISO-fuzzy controller based on triple Ⅰ algorithm is investigated. It is pointed out that if Ri (i= 1,2,3) takes R0, RM, Rz in turn, SISO-fuzzy controller based on triple Ⅰ algorithm is of interpolation property. If Ri (i= 1,2,3) takes RM, Re, Rz or R0, Re, RM, respectively, SISO-fuzzy controller based on triple Ⅰ algorithm is unary fitting function, approximately. Others are only of step output property.
