Abstract

In this paper, a robust H$_{infty}$ state-feedback controller providing optimal stability as well as robust performance suitable for implementation in DC-DC converters is proposed. Under disturbances arising from variations in input voltage and load, and uncertainties from converter's parameters, the suggested control approach is developed to obtain the state-feedback gain by means of linear matrix inequality constraints based on Lyapunov stability theory. The performance of the designed controller under various scenarios is presented using experimental setup. The obtained results affirm the efficacy of the suggested design methodology.
