Converter switching mechanism scheduling by type-2 fuzzy approach for PV/battery/Fuel systems

In this paper a type-2 (T2) fuzzy logic system (FLS) based controller is presented for power/voltage control of PV/batery/Fuel system. The switching mechanism of the converters are adjusted by the use of FLS based controllers. The rules of T2-FLSs are tuned on basis of Lyapunov approach. The tuning rules are determined such that the stability to be ensured and also the regulation to be obtained. Simulations verify that the deigned controllers result in a desired regulation in versus of fully unknown dynamics of PV and all other units and also the obtained control signals have a desired implementable shape.
