Summary: This paper presents a systematic approach to synthesize constant power loads using switching converters under sliding-mode control, analyzing the generation of sliding motions and establishing the existence conditions for sliding-mode and stability of the resulting ideal dynamics. Simulation and experimental results verify the theoretical predictions, illustrating a simple, economical, and small-size prototype for experimental validation of converters supplying constant power loads.

Summary: This article proposes a global optimal cooperative control strategy to improve the poor dynamic consensus in multiple dc-dc converter systems caused by parameter differences. The proposed control strategy achieves dynamic consensus of output currents by minimizing a global performance index, and introduces integral action and nonlinear coordinate transformation techniques to improve coordinated performance. Proof of stability and consensus is provided using Lyapunov approach, and design guidelines for tuning dynamic response are given through simulations.
