[0013] Therefore, if a more general expression is used, even if the idea disclosed in Patent Document 1 is used to maintain or control the control amount of the control object to the initial target value, it will not be possible to use it due to the state of the entire system including the control object. A control method suitable for the initial target value to maintain or control the controlled amount of the controlled object, or the control of the controlled amount of the controlled object is not an appropriate control method for the entire system including the controlled object
[0014] In addition, in the temperature control device described in Patent Document 1, when there are control objects other than the heating plate, that is, when there are a plurality of control objects, when each control object is affected by external disturbances, it is desired When the control amount of each control object is maintained or controlled by the control method of the initial target value, for the same reason as above, the control amount of each control object cannot be maintained or controlled by the control method suitable for each initial target value, The control of the control amount of each control object is not an appropriate control method for the system as a whole including these control objects

Embodiment Construction
[0078] Hereinafter, embodiments of a control device for an internal combustion engine according to the present invention will be described with reference to the drawings. The embodiments described below apply the control device of the present invention to figure 1 The embodiment shown is an internal combustion engine.
[0079] figure 1 The shown internal combustion engine 10 includes: a main body of the internal combustion engine (hereinafter referred to as “engine main body”) 20 , fuel injection valves 21 arranged corresponding to the four combustion chambers of the internal combustion engine main body 20 , and injecting fuel to the fuel through a fuel supply pipe 23 . Valve 21 supplies fuel to fuel pump 22 . Furthermore, the internal combustion engine 10 includes an intake system 30 for supplying air to the combustion chamber from the outside, and an exhaust system 40 for discharging exhaust gas discharged from the combustion chamber to the outside. In addition, the inter...

In the case where a constraint condition related to an internal combustion engine is satisfied when a control amount of each of the control objects 35d, 52 is controlled in accordance with the operation amount determined based on initial target values TPcom and TRegr of respective control objects of an internal combustion engine 10, the control amount of each of the control objects is controlled in accordance with the operation amount determined based on the initial target values. In the case where the constraint condition is not satisfied, the initial target values are repeatedly corrected in accordance with a predetermined rule so as to satisfy the constraint condition, and the control amount of each of the control objects is controlled in accordance with the operation amount determined based on the corrected initial target values.
Description
technical field [0001] The invention relates to a control device for an internal combustion engine. Background technique [0002] Patent Document 1 describes a temperature control device that controls the temperature of a heating plate on which a semiconductor wafer is mounted. In this temperature control device, the heating plate is heated by the heater, and as a result, the semiconductor wafer mounted on the heating plate is heated. And the temperature control device controls the heating operation of the heater so that the temperature of the heating plate becomes the target temperature. [0003] However, in the temperature control device described in Patent Document 1, if the heating plate is affected by external disturbances, the temperature of the heating plate becomes higher or lower than a target temperature (hereinafter referred to as “initial target temperature”). That is, if the heating plate is affected by external disturbances, the temperature of the heating pla...
