I am using Fuzzy Logic Controller in MATLAB R2017a. Here's my code for controller.
[System]
Name='Fuzzy_Controller'
Type='mamdani'
Version=2.0
NumInputs=1
NumOutputs=3
NumRules=5
AndMethod='min'
OrMethod='max'
ImpMethod='min'
AggMethod='max'
DefuzzMethod='centroid'
[Input1]
Name='e'
Range=[-1 1]
NumMFs=5
MF1='NB':'trimf',[-1 -1 -0.7]
MF2='NM':'trimf',[-0.8 -0.5 -0.2]
MF3='Z':'trimf',[-0.3 0 0.3]
MF4='PM':'trimf',[0.2 0.5 0.8]
MF5='PB':'trimf',[0.7 1 1]
[Output1]
Name='Kp'
Range=[-5 5]
NumMFs=5
MF1='NB':'trimf',[-5 -5 -3.45]
MF2='NM':'trimf',[-4.2 -2.5 -0.8]
MF3='Z':'trimf',[-1.6 0 1.6]
MF4='PM':'trimf',[0.75 2.5 4.2]
MF5='PB':'trimf',[3.4 5 5]
[Output2]

MF3='Z':'trimf',[-0.085 0 0.08]
MF4='PM':'trimf',[0.04 0.125 0.215]
MF5='PB':'trimf',[0.17 0.25 0.25]
[Output3]

NumMFs=5
MF1='NB':'trimf',[-1 -1 -0.69]
MF2='NM':'trimf',[-0.84 -0.5 -0.16]
MF3='Z':'trimf',[-0.33 0 0.33]
MF4='PM':'trimf',[0.16 0.5 0.85]
MF5='PB':'trimf',[0.65 1 1]
[Rules]

3, 3 3 3 (1) : 1
4, 4 4 4 (1) : 1
5, 5 5 5 (1) : 1
But When I execute this controller, It gives me this error: How do I correct this.
Error in 'model3_FUZZY/Fuzzy_PID_Controller/Fuzzy_Controller': Initialization commands cannot be evaluated.
Caused by:
Struct contents reference from a non-struct array object.
