Abstract
A system for driving an actuator which is capable of providing constant resolution regardless of a type of an actuator according to an aspect of the present invention includes an actuator driving circuit configured to generate a driving current for an operating actuator and output the generated driving current to the operating actuator, a current sensing unit configured to sense a current of the operating actuator and generate a sensing signal, and a gain adjustment unit configured to calculate a gain on the basis of a first maximum driving current range of the operating actuator and a second maximum driving current range of a reference actuator and change the sensing signal on the basis of the gain. A signal generated based on the second sensing signal is input to the actuator driving circuit.
