A novel adaptive output feedback control for DC–DC boost converter using immersion and invariance observer

Abstract

This paper presents a class of novel adaptive output feedback controller for DC–DC boost converter with global exponential stability. In addition, the control input constraint is considered in stability analysis. The proposed adaptive control scheme is constructed to estimate input voltage and inductor current using output voltage and control signal information. In order to estimate unavailable state and parameter, immersion and invariance technique is employed. The effectiveness of the proposed method is investigated via experimental test and the practical results endorse the efficiency of this adaptive controller.
