Design for Nonlinear Current Reference Deadbeat Control for Boost Converter

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.
