document: Robust fuzzy controlled photovoltaic power inverter with Taguchi method This paper presents design and implementation of a robust fuzzy controlled photovoltaic -LRB- PV -RRB- 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 -LRB- Intel 80196KC -RRB- are presented to verify the theoretical discussions , and its adaptivity , robustness and feasibility
