A filter-based controller for a buck converter

Abstract:

A filter-based control scheme is developed for buck-Type converters. This approach relies only on a single output voltage measurement. The benefits of this approach are reducing the system cost as well as measurement noise and disturbance injected by output current and/or inductor current measurements. A Lyapunov stability analysis is utilized to demonstrate system stability. Experimental results demonstrate excellent voltage regulation and insensitivity to the load variations.
