Abstract
A drive circuit () of an actuator () calculates an actual working angle from an actual operation quantity with reference to a reference table used to calculate a target operation quantity, and transmits the actual working angle and the actual operation quantity to a command unit (). The command unit () determines whether or not the received values of the actual working angle and the operation quantity correspond to the valve working angle and the operation quantity of the reference table stored in the command unit (), to detect a discrepancy between the operation modes of the actuator () and the command unit ().
