Zusammenfassung:	The invention discloses a control method of a full-bridge DC-DC system based on on-chip model predictive control. The control method includes following steps: (1) dividing an object state of the non-linear full-bridge DC-DC system into different polyhedral areas, and obtaining a best control law according to the control laws in each polyhedral area; (2) storing edge constraint conditions of each polyhedral area and the best control law in step (1) into a control chip of the on-chip model predictive control; (3) inquiring the corresponding area in the control chip according to the actual object state of the non-linear full-bridge DC-DC system, and then controlling a feedback control input of the full-bridge DC-DC system according to the best control law in the polyhedral areas. By the control method, rapid control of the full-bridge DC-DC system is realized and robustness is strong.
