Abstract
For an easily implementable method for model predictive control of a DC/DC converter, and a corresponding controller, with which the optimization problem of the model predictive control can also be solved sufficiently quickly with large prediction horizons, the optimization problem is divided into two optimization problems by a model predictive output variable control and a model predictive choke current control being implemented in the control unit (), wherein: the strands of the multiphase DC/DC converter () for the output variable control are combined into a single strand; a time-discrete state space model is produced therefrom; and the output variable control predicts the input voltage (u) of the next sampling step (k+1) for this single strand on the basis of a first cost function (J) of the optimization problem of the output variable control, said input voltage being given to the choke current control as a setpoint and the choke current control determining therefrom the necessary switch positions of the switches (S, S, S, S, S, S) of the strands of the multiphase DC/DC converter () for the next sampling step (k+1) on the basis of a second cost function (J) of the optimization problem of the choke current control.
