【求助】问题求助！！
 

大家好，我在做一个自动控制的仿真时，使用了模糊控制器这个仿真元件，还有MUX，但是结果出错，下面是错误出现时的说明：
第一个是MinMax blocks do not accept 'boolean' signals. The input signal(s) of block 'mkkzq1/Subsystem/Fuzzy Logic Controller with Ruleviewer/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
第二个是An error occurred while propagating data type 'boolean' from block 'mkkzq1/Subsystem/Fuzzy Logic Controller with Ruleviewer/Fuzzy Logic Controller/FIS Wizard/Defuzzification1/Zero Strength (COA)', output port 1。
希望得到能人相助，先谢谢了
