To apply model prediction control even to a system in which it is difficult to directly adopt model prediction control.
In this system constituted of a fuel battery stack and its auxiliary machine, the target value of the auxiliary machine is set large (S1), and the target value is optimized by using the model of the fuel battery stack (S2). Then, the manipulated variables of the auxiliary machine are optimized by using the model of the auxiliary machine so that the optimized target value can be satisfied (S3). Furthermore, vehicle fuel consumption is calculated from the optimized manipulated variables of the auxiliary machine, and the manipulated variables of the auxiliary machine are optimized again under the consideration of this, and the optimized manipulated variables are applied to a real machine.
