Abstract
Description
This paper describes a design for fast and robust nonlinear deadbeat control for boost DC–DC converters. Nonlinear current reference deadbeat control is derived based on nonlinear state equation of the converter. Load disturbance compensation is implemented thus forming a new robust nonlinear controller. Both experiments and simulations of boost converter with input 12 V, output 20 V, load 4 Ω and 100 kHz sampling frequency, confirmed the voltage command tracking capability 266 μs settling time, and also disturbance rejection 1.20 ms recovery time. The method is applicable to boost converters of various applications.
