Abstract
A compensation method of an actuator system for a clutch may compensate initial operating position of an actuator that may be changed due to abrasion so that may maintain stroke distance of a clutch stable. The compensation method includes determining a target pressure if operating requirement of a clutch is detected and operating an actuator according to the target pressure, determining whether operating movement of the actuator is strayed from a predetermined value if operating pressure of the actuator reaches the target pressure, determining error of initial operating position of the actuator if the operating movement of the actuator is strayed from the predetermined value and determining compensating ratio according to the detected position deviation of the error and compensates the initial operating position of the actuator by controlling a lead screw of the actuator according to the determined compensating ratio.
