How to reduce the simulation running time when fuzzy block gets included?

Im doing three phase grid control of PV systems. while using conventional PI block, it takes less time to run the simulation. But when i use fuzzy block with the same simulation file, the running time of simulation is too high. Please anyone help me to resolve this issue.

Hi @MALARVILI S

I guess that your designed Fuzzy System is a Mamdani-type FIS, and it has too many Rules for the program to evaluate them all at once. On the other hand the PI (Proportional–Integral) is just a 2-term mathematical law that governs how the action should be applied to the grid connected PV system.

Though I don't know how you govern the Rules using your PV expertise knowledge, I will fuzzily translate a working PI mathematical law into a few logical rules using the Sugeno-type FIS, and then reshape the input membership functions in the way that will improve the performance of the grid connected PV system.
