Design the Fuzzy Logic Controller

Objective
To design the FLC using the MATLAB applications.

Activity
Design the FLC in MATLAB applications with 2 input which is error and change of error and the output will be voltage. The membership functions of system is designed in MATLAB. The rules of the fuzzy is decided in MATLAB.

Membership function for first input (error)

Membership function for second input (change of error)

Membership function of the output

Analysis

To design all the membership functions need a very long time because there is no systematic procedure to design  the membership function like to know the limit range, how many membership function needed and many more. So, it need try and error procedure which is time consuming. We need to try every possible way to make it work properly.
