Robust Control of Switched Reluctance Generator In Connection With a Grid-Tied Inverter

This paper presents a robust control of a switched reluctance generator in connection with a L-filtered grid-tied inverter for wind power generation. A sliding mode controller is used in order to regulate the DC link voltage. The design procedure as well as the stability analysis are presented. A robust state-feedback controller is designed based on LMIs, aiming to synthesize a grid-injected current, ensuring suitable performance and stability for the entire range of uncertain grid inductance. Simulation result are shown in order to demonstrate the DC link voltage regulation as well as the grid injected currents.
