MAXIMUM POWER POINT TRACKING CONTROL OF PHOTOVOLTAIC ARRAY USING FUZZY NEURAL NETWORK

  • Published : 1998.10.01

Abstract

Solar cell has an optimum operating point to extract maximum power. To control operating point of the solar cell, a fuzzy controller has already been proposed by our research group. However, several parameters are determined by trial and error. To overcome this problem, this paper adopts Fuzzy Neural Network (FNN) for maximum power point tracking control for photovoltaic array. The FNN can be trained to perfect fuzzy rules and to find an optimum membership functions on-line.
