设计的模糊控制器无法仿真
 

我做的毕业设计要用到模糊控制器，我现在做好了，拉到Simulink里仿真的时候报错如下：1.untitled8/Fuzzy logic Controller/FIS wizard/Defuzzication1/Max(COA)
MinMax does not accept 'boolean' signals. The input and output signal(s) of 'untitled8/Fuzzy Logic Controller/FIS Wizard/Defuzzification1/Max (COA)' must be one of the MATLAB 'uint8', 'uint16', 'uint32', 'int8', 'int16', 'int32', 'single', or 'double' data types, or one of the Fixed-point data types
2.untitled8/Fuzzy logic Controller/FIS wizard/Defuzzication1/zero Strength(COA)
An error occurred while propagating data type 'boolean' from 'untitled8/Fuzzy Logic Controller/FIS Wizard/Defuzzification1/Zero Strength (COA)', output port 1请问我该在哪解决这个问题呢？
