ABSTRACT:
A control apparatus for an internal combustion engine includes an oil pressure regulating valve having a solenoid, a variable cam phase mechanism for changing a cam phase, and an ECU for controlling the oil pressure regulating valve. The ECU includes an actual cam phase detecting unit, a target cam phase setting unit, a feedback control unit, a coil temperature detecting unit, a circuit resistance calculating unit, and an integral term initial value calculating unit. When an integral term is initialized, the feedback control unit sets the holding output duty as the integral term.
