Deadbeat control of an AC-DC converter

A structure of an AC-DC converter control system based on a deadbeat controller that allows to obtain a finite duration transient in the small neighborhood of an equilibrium state is offered. The key feature of this deadbeat controller is that it enables to reduce a system matrix to the Frobenius form without transformation of variables as contrasted to the known variant of a deadbeat controller. A design procedure to obtain deadbeat controller parameters for one-phase controlled rectifier used for stabilizing a current in an active-inductive load is stated. Simulation of the converter transients during current reference step changes is given to demonstrate high efficiency of the proposed deadbeat controller.
