ĆUK CONVERTER CONTROL WITH A ROBUST INTEGRAL SWITCHING CONTROLLER
A robust control strategy for constant voltage reference tracking control of the Ćuk converters is presented in this study. The Ćuk converter can find many application places in industrial systems, but its topology has a non-minimum phase uncontrollable nonlinear dynamics, which poses problem in a low cost and high performance control design specifically under load/supply variations. An integral switching controller is designed to achieve robust operating conditions. The state averaging method and variable structure system theory are used in the design and analysis of the controller. The performance of the controlled Ćuk converter is evaluated via numerical simulations and circuit realizations to show the validity, feasibility and robustness of the controller.
