Gain-scheduled frequency control in a microgrid

This paper proposes a robust H∞ static output-feedback (SOF) controller design method for microgrid using Linear Parameter-Varying (LPV) approach. The proposed controller is designed to not only ensure a good frequency response with disturbance rejection, but also to provide the robustness in despite changes of the inertia of the grid. Two scenarios are studied in simulation to show the good steady-state and dynamic behaviours of the closed-loop system.
