Abstract
The invention relates to a sliding mode controller for controlling a controlled object system by using the adaptive sliding mode control. Also, the invention relates to an internal combustion engine system control device for controlling an internal combustion engine system by using the adaptive sliding mode control. The invention is characterized by comprising adaptive law input term learning means for learning an adaptive law input term so as to transfer an offset of a reaching law input term in the adaptive sliding mode control to the adaptive law input term.
Claims5
A sliding mode controller applied to a controlled object system including at least one controlled object,
- the sliding mode controller comprising:
- an electronic control unit configured to control the controlled object system by an adaptive sliding mode control including a linear input term, a non-linear input term, and an adaptive term;
- means configured to acquire an operation state of the controlled object system;
- and
- means configured to control the operation state of the controlled object system,
- wherein the electronic control unit is configured to:
- learn the adaptive term by adding one of a value of the non-linear input term and a predetermined proportion of the value of the non-linear input term to the adaptive term when the operation state of the controlled object system changes from a transient state to a stationary state;
- correct the non-linear input term by subtracting the value added to the adaptive term from the non-linear input term;
- and
- control the controlled object system by the adaptive sliding mode control using the learned adaptive term and the corrected non-linear input term.
