Abstract
This paper describes a novel stabilising control strategy for DC power systems with constant power loads. The destabilising element associated with a constant power load is eliminated by reformulating the system dynamic equations in terms of the rate of change of energy, or instantaneous power. A power shaping control strategy is employed to regulate the output voltage, while maintaining large-signal system stability under all operating conditions. The proposed control strategy is simple, and easy to design and implement. Its utility and effectiveness are demonstrated by simulations and experiments.
