title: Robust fuzzy controlled photovoltaic power inverter with Taguchi method
abstract: This paper presents design and implementation of a robust fuzzy controlled photovoltaic (PV) power inverter with Taguchi tuned scaling factors. To achieve fast transient response, small steady-state error and system robustness, a robust fuzzy controller is adopted, in which its input and output scaling factors are determined efficiently by using the Taguchi-tuning algorithm. The proposed system can operate in different modes, grid-connection mode and stand-alone mode, and can accommodate wide load variations. Simulation results and hardware measurements obtained from a prototype with a microcontroller (Intel 80196KC) are presented to verify the theoretical discussions, and its adaptivity, robustness and feasibility
