Abstract: The present invention relates to a haptic feedback system and, specifically, to a device and method for controlling an actuator for haptic feedback, the method comprising: an actuator resonance frequency correction driving step of driving an actuator by repeatedly generating and outputting a drive signal including a driving time interval in which driving voltage is applied to the actuator and a guard time interval in which a back electromotive force (BEMF) signal of the actuator is detected, while correcting the length of the driving time interval according to detection time of a zero cross point of the BEMF signal detected within the guard time interval; and an actuator braking step of outputting at least one brake signal in synchronization with a zero cross point of the BEMF signal detected within the guard time interval, in order to remove residual vibration of the actuator.
