What are fuzzy logic controllers & how do they work?

Why do we need fuzzy controllers?

This is due to the fact that fuzzy controllers take into account in the decision making the technical operational limits of the electrical system under study, such as violations of the voltages in the buses, state of charge (SOC) of the EV batteries, and the power flows, for this time elapsed of the fuzzy controllers required 9.58 s.
