This paper presents the fuzzy control of switching Photovoltaic (PV) DC-DC power converters subject to parameter uncertainties and the state variables unavailable for measurements based on the Takagi- Sugeno (TS) fuzzy modeling approach. First, we derive the TS model for the switching converter. Second, a nonlinear robust fuzzy controller is designed accordingly. The TS fuzzy model is adopted for fuzzy modelling of the nonlinear system and establishing fuzzy state observers. The concept of General Design Approach (GDA) is employed to design fuzzy control and fuzzy observers from the TS fuzzy models. The proposed algorithm regulate the produced voltage and able to maintain the system stable during the parameter uncertainties. The design procedures are applied to a dynamics model of typical PV power control system using a DC-DC buck converter to illustrate the effectiveness of the proposed control techniques.
