This paper proposes a fast and robust nonlinear deadbeat control for boost DC-DC converters. First, the nonlinear state equation is derived, and second a nonlinear current reference deadbeat control is proposed. Third, a new nonlinear controller to implement the load disturbance compensation is proposed. After the simulations and verification by experiments, it was confirmed that under the conditions of an input voltage of 12V, an output voltage of 20V, a load resistance of 4Ω and a sampling frequency of 100kHz, the voltage command tracking capability of a settling time of 280µs was achieved, and an output voltage recovery time of 1.46ms was achieved for a sudden load change.
