Adaptive partial state feedback control of the DC-to-DC Cuk converter

The problem of output voltage regulation by means of partial state and parameters information for the DC-to-DC Cuk converter is addressed and solved. It is shown that the combination of a full information controller with a stable state and parameters estimator, designed using the immersion and invariance technique, yields a globally asymptotically stable closed-loop system. A few simulations complete the paper.
