Abstract:
1. A control apparatus for an internal combustion engine which is capable of changing an operating characteristic of the internal combustion engine by means of an actuator, the apparatus comprising: a crank angle sensor that detects a crank angle of a crankshaft of the internal combustion engine and generates a crank angle signal; an actual operating characteristic detection section that detects an actual value of the operating characteristic as an actual engine operating characteristic; an operating condition detection section that detects an operating state of the internal combustion engine; a target operating characteristic calculation section that calculates a target value of the operating characteristic as a target operating characteristic based on the engine operating state; and an operation amount feedback control section that calculates an amount of operation with respect to the actuator according to feedback control so as to make the actual operating characteristic and the target operating characteristic coincide with each other; wherein the operation amount feedback control section calculates the amount of operation in synchronization with the crank angle signal.
