This paper proposes a fast and robust nonlinear deadbeat control for boost DC–DC converters. First, the nonlinearstate equation is derived, and second a nonlinear current reference deadbeat control is proposed. Third, a new nonlin-ear controller to implement the load disturbance compensation is proposed. After the simulations and verification byexperiments, it was confirmed that under the conditions of an input voltage of 12 V, an output voltage of 20 V, a loadresistance of 4Ωand a sampling frequency of 100 kHz, the voltage command tracking capability of a settling time of280μs was achieved, and an output voltage recovery time of 1.46 ms was achieved for a sudden load change.
