Abstract:
An apparatus for controlling an internal combustion engine by generating a command value for a manipulative quantity of a flow control valve disposed in an intake air passage of an internal combustion engine controllable by the flow control valve, according to a sliding mode control process in order to converge a predetermined control quantity relative to the internal combustion engine to a target value thereof, wherein an object to be controlled by the sliding mode control process is modeled by a discrete system for generating said control quantity from the command value for the manipulative quantity of said flow control valve, said sliding mode control process uses a switching function constructed by a linear function composed of a plurality of time-series data of the difference between said control quantity and said target value, and an algorithm for generating the command value for the manipulative quantity of said flow control valve in a predetermined control cycle according to said sliding mode control process is constructed based on the discrete-system model of said object to be controlled and said switching function.
