A control apparatus for an internal combustion engine can control an actual operating characteristic with high precision by shortening a response time thereof. The control apparatus capable of changing an actual phase angle of a camshaft by an OCV includes a crank angle sensor for detecting a crank angle of a crankshaft and generating a crank angle signal, an actual phase angle detection section for detecting the actual phase angle of the camshaft, an air flow sensor and a throttle position sensor for detecting an operating state of the engine, a target phase angle calculation section for calculating a target phase angle based on the operating state, and a phase angle feedback control section for calculating an operation amount to the OCV so as to make the actual phase angle coincide with the target phase angle. The phase angle feedback control section calculates the operation amount in synchronization with the crank angle signal.
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:
