A Robust H_∞ State Feedback Controller For Mppt Control Based On The Mean Value Theorem

This paper presents a new strategy for a maximum power point (MPP) tracking MVT controller for photovoltaic (PV) systems subject to atmospheric condition variations. A DC-DC boost converter is used to connect a PV panel with an output load. The output voltage of the DC-DC boost converter can be adjusted by duty ratio that is limited between two values. The objective of our control design is to track the MPP. To minimize and stabilize the tracking error with disturbance effect, the dynamic behaviour of a PV system and its reference model are described by using men value theorem (MVT) and sector linearity’s (SNL). Then, a robust PI-controller based on state feedback control is proposed. The control approach design is used to establish the stability conditions of the closed-loop system which is formulated and solved using Lyapunov theory that are transformed in terms of linear matrix inequalities LMI s. Finally, simulation results are given to show the tracking performance of the control design.
