The purpose of this study is to construct a system for tracking the maximum power point of a photovoltaic power generator that copes with changing system characteristics according to environmental changes. The proposed system is divided into two subsystems: one is the control system for determining switch duty ratio of a DC/DC converter and the other is an estimator of the photovoltaic power generator characteristics using an adaptation mechanism. The mathematical model of the characteristics of the controlled object is assumed to be a 4th -order polynomial and its parameters are regulated by an adaptive algorithm every sampling time. Thus, the non-linearity of the controlled object and its characteristic changes due to external environment changes are regarded as deviations of the parameters of the mathematical models by the concept of the adaptive system. The proposed system is confirmed to be useful for the tracking of the maximum power point of a photovoltaic power generator in conditions of changing environments.
