Maximum power point tracking control of solar power generation systems based on type-2 fuzzy logic

This paper has proposed maximum power point tracking (MPPT) control for stand-alone solar power generation systems via the type-2 Takagi-Sugeno (T-S) fuzzy-model-based approach. In order to deal with the uncertainties in the modeling procedure, the type-2 T-S fuzzy technology is employed. To handle reducing the conservatism of LMI-based stability conditions for type-2 T-S fuzzy systems, stability conditions are relaxed by introducing more slack matrix variables. Finally, the control performance is shown from the numerical simulation and experimental results.
