<p><P>PROBLEM TO BE SOLVED: To provide a model prediction controller cutting off an upper model prediction control system for safety to smoothly transfer to control of only a lower control system and continuing the control, when some trouble on control calculation occurs during execution of model prediction control. <P>SOLUTION: This model prediction controller is constituted of a target value generator 10, a model prediction controller (MPC) 20, a switch 100, a lower controller (LC) 30, and a control target (P) 40. Normally, a switch signal FLG_LC is placed in a state that a flag is 0, and optimization processing by the MPC 20 is executed. When it is decided that a situation that an execution time is not stored within a control period occurs because the optimization processing inside the MPC 20 becomes worse, the MPC 20 switches the flag of the switch signal FLG_LC to 1. The flag "1" is transmitted to the switch 100, and the switch 100 smoothly transfers to a state of only the lower control system from a state of MPC 20 use. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
