I. Introduction
Fuzzy logic is a widely used artificial intelligence in industnal [1] , [2] which improves the adaptiveness of control systems in various engineering areas, such as traffic signal control [3] , optimizing photovoltaic (PV) array [4] and battery charging control [5] . One of the weaknesses of fuzzy logic is this algorithm implements the deterministic computational technique to make deductions or narrow down the control solutions. This limits the exploration of the algonthm for seeking the optimum solution because every control decision is precisely calculated based on the predefmed rules and membership functions [6] .
