| description | The invention relates to the technical field of power electronic control, and particularly relates to a finite time control method based on Buck converter current limitation. The method comprises thesteps of S1, obtaining an average mathematical model based on a DC-DC Buck converter, and obtaining a state expression and an error dynamic equation; S2, designing a current-limited finite time controller, and substituting the control input [mu] of the DC-DC Buck converter into the error dynamic equation; and S3, designing an adaptive current limited finite time controller. The method has the advantages that a finite time control algorithm is adopted, so that rapid tracking of the voltage can be realized, the convergence speed is increased, and the robustness of the system can be improved. Dueto the fact that current limitation is adopted, it can be guaranteed that the current is controlled within a certain range, and the circuit is protected against damage caused by overlarge current.
