How to replace PID controller with fuzzy controller so that it can work exactly the same as PID

I have a model in simulink as shown

The model has PID controller with Kp=36 Kd=54 Ki=6. Pid controller is minimizing the error given as its input to zero. Now I want to replace it with fuzzy controller so that it exactly works the same as PID. What to do?

Its very simple .... In Matlab workspace type fuzzy . Fuzzy toolbox will open. You are required to assign the Inputs and Outputs there. Make Error e and Change in error de as inputs nad Kp , Ki, and Kd as Outputs. Then decide the range for each of of the membership functions of these inputs and outputs. [Refer some research paper for details]

Save the model as Model.fis and export this model to workspace.

Open the Simulink and like as the figure you have posted replace it with Fuzzy Logic Controller Block and call the Model.fis in block. and run the simulation. :)
