Abstract

A control device (10) for an internal combustion engine (2) includes at least one processor (12) and a memory (14) configured to store a program. The at least one processor (12) is configured to execute, by executing the program, a process of deciding a manipulated variable of the internal combustion engine from a control input value, in accordance with a predetermined conversion rule, a process of calculating a sample value of the controlled variable, a process of calculating a reference expectation value of the controlled variable from the control input value, a process of performing a hypothesis test for a null hypothesis that an average value of a predetermined number of recent sample values of sample values of the controlled variable is equal to the reference expectation value, and aprocess of modifying the conversion rule by an adaptive control when the null hypothesis is rejected.

Description

technical field [0001] The present invention relates to a control device for an internal combustion engine, and more specifically, to a control device for an internal combustion engine and a control method for an internal combustion engine suitable for use in controlling a control object having a probability deviation. Background technique [0002] In the case of applying feedback control to the controlled variable of the control object having a probability deviation, conservative control has to be performed in order to prevent excessive control caused by the deviation of the control object. However, in conservative control, it is difficult to ensure quick responsiveness to changes in the control amount. [0003] The change of the control quantity includes the change caused by the inherent probability deviation of the system and the change caused by factors other than the probability. A change in the control quantity to be handled by the feedback control is a change in the ...
