Abstract

This paper proposes an optimal regional pole placement approach for sun tracking control of high-concentration photovoltaic systems. A static output feedback controller is designed to minimize an LQG cost function with a sector region pole constraint. The problem cannot be solved by LMI approach since it is a non-convex optimization problem. Based on the barrier method, we instead solve an auxiliary minimization problem to obtain an approximate solution. Simulation results show the benefit of our approach.
