Deadbeat control method and device of Boost converter, electronic equipment and storage medium

Abstract

The embodiment of the invention belongs to a deadbeat control method and device for a Boost converter, electronic equipment and a storage medium. The method comprises the steps of: carrying out parameter identification on the internal resistance of an inductor in the Boost converter based on a least square parameter identification algorithm in a current switching period, and obtaining an identification value of the internal resistance of the inductor; performing operation on the circuit parameters of the Boost converter in the current switching period, the identification value of the internal resistance of the inductor in the Boost converter and a preset inductive current instruction value based on a dead-beat control algorithm, so as to obtain a first predicted duty ratio of a switching tube in the Boost converter; and determining the duty ratio of the switching tube in the Boost converter in a second switching period after the current switching period based on the first predicted duty ratio. Therefore, parameter identification is carried out on the internal resistance of the inductor, so that the identification value of the internal resistance of the inductor can be equal to the true value of the internal resistance of the inductor as far as possible, so that the steady-state static error of the output voltage in a circuit can be solved; the duty ratio is obtained through calculation based on the identification value of the internal resistance of the inductor, so that adjustment of the duty ratio is achieved.
