A self-compensating adaptive digital regulator for switching converters based on linear prediction

This paper presents a self-compensating adaptive digital regulator applied to dc to dc converters. Implementing linear prediction, it adapts online, and may be operated continuously, characterizing disturbances in the loop, allowing optimal disturbance rejection. A dual purpose controller-predictor provides robust performance in low complexity hardware.
