Evaluation of control strategies applied in small-scale photovoltaic solar tracking systems: a review

Abstract This work evaluates the control algorithms applied to decentralized photovoltaic solar tracking systems. For this, strategies are divided into three: open loop, closed loop and hybrid loop. Each strategy is screened for its suitability as a suitable technology small-scale applications, defined by meeting set of eleven attributes. A specialized literature review process was developed specifically present potential each algorithm strategy, through an evaluation matrix. The analysis attributes carried out using formal methodology concept analysis. To facilitate processing information, free access software called “concept Explorer” used. shows that currently have greater application in one two-axis Additionally, on-off with greatest three types loops evaluated.
