摘要

The negative impedance caused by constant power load (CPL) may lead to the instability of overall power system. In this article, the regulation problem of output voltage of dc-dc converters subject to unknown CPLs is addressed. Our main contribution in this article is to design an adaptive energy shaping control (ESC) algorithm, which combines passivity theory with immersion and invariance technology, to stabilize dc-dc buck converter and boost converter with CPLs, respectively. Three good features of the proposed control method are that (1) the stability analysis and controller design are based on large signal model, (2) the proposed control scheme is implemented without needing the knowledge of power load, and (3) the estimation of domain of attraction is presented to guarantee strictly the asymptotic convergence of closed-loop system. The performance of the proposed controller is assessed via detailed simulation and experimental results.
