A control system for an internal combustion engine having a plurality of cylinders and an engine control module is disclosed. Each cylinder has at least one intake valve and one exhaust valve. Each valve is actuated by an electromagnetic valve actuator. The servo control system includes a control module and a power module. The control module includes an electronic control unit coupled to the engine control module for receiving engine sensor information, a servo board coupled to the electronic control unit for receiving a command signal and sending delay feedback signals to the electronic control unit, and a demodulation board coupled to the servo board for sending a voltage signal proportional to the valve position to the servo board. The power module is coupled to the electromagnetic valve actuator and the control module and provides current output to the electromagnetic valve actuator and sends a current monitor signal proportional to the current output back to the control module of the control system.
