Abstract: The present invention relates to a haptic feedback system and, particularly, to a device and a method for controlling an actuator for haptic feedback, the method comprising: a first step of controlling the output of an oscillator such that a clock necessary in the generation of a driving signal for driving an actuator is oscillated at a reference clock frequency; a second step of calculating the resonance frequency of the actuator from a cycle of a BEMF signal according to the driving of the actuator; and a third step of calculating a clock frequency for following the calculated resonance frequency of the actuator so as to newly change and set same to the reference clock frequency, thereby controlling the output of the oscillator.
