| description | The invention discloses a model prediction control method and a model prediction control device for a dual-active bridge converter, which are used for solving the problems of low transmission efficiency, large power conversion loss and large transformer current stress in the existing related method. Comprising the steps that a predictive control model of the dual active bridge converter, a target cost function and a moving discrete control set at the end moment of a d period are acquired, and the target cost function is constructed based on the minimum voltage predictive error, the minimum voltage change and the minimum current stress as control constraints; the mobile discrete control set comprises a plurality of candidate search points, and each candidate search point corresponds to one control variable combination; according to the predictive control model, calculating an output voltage predictive value of each candidate search point at the end moment of the (d + 2) th period; and for each candidate search |
