ROBUST CONTROL DESIGN FOR BOOST CONVERTERS USING LMI TECHNIQUE

Electrical Engineering

In this paper, a robust control design for boost regulators based on the linear matrix inequalities (LMI) technique is investigated. Authors presented nonlinear terms as a convex polytope for designing a robust state-feedback controller in the vertex system using the LMIs technique. This work extends the regional pole placement problem to improve the transient behavior of the system based on polytope and LMIs properties. By introducing or manipulating some existing parameters, the controller can be designed in such a manner that varying values of these parameters indicate various regions where the closed-loop poles are located. MATLAB simulations are performed to validate this approach, and the findings are comparable to those of a PID controller.
