Abstract

While solar energy is accepted as an abundant source of energy, it is stochastic in nature, unlike many other conventional sources of energy. This intermittency requires robust controllers that allow for maximized energy harvest. A general trend to improving controller design is to consider modern control techniques, particularly optimal control methods like model predictive control (MPC). While these techniques offer faster and more accurate reference tracking, they also add to the complexity of the system and could possibly reduce its window of stability. This paper is comprised of further analyses of the previously proposed sensorless current mode (SCM) controller for the photovoltaic maximum power point tracker (MPPT) based on MPC. Through a variety of parameter mismatch and sensitivity studies, a better perspective on the stability and efficacy of the proposed control method is presented.
