Lyapunov-Based Control for Switched Power Converters

Abstract

Beginning with fundamental properties such as passivity or incremental passivity of the network elements comprising a switched power converter, the nominal open-loop operation of a broad class of such converters is shown to be stable in the large via a Lyapunov argument. The obtained Lyapunov function is then shown to be useful for designing globally stabilizing controls that include adaptive schemes for handling uncertain nominal parameters. Numerical simulations illustrate the application of this control approach in DC-DC converters.
