The present invention relates to a controller for compensating a clearance of a speed reducer, a clearance compensation system for the speed reducer, and a method thereof, wherein the clearance compensation system for the speed reducer includes: a worm shaft connected to a first shaft to receive rotational force; a worm wheel for transmitting the rotational force to a second shaft in engagement with the worm shaft; a controller for recognizing a rattle mode based on a torque signal output from a torque sensor and outputting a rattle reduction control signal for reducing rattle caused by the clearance between the worm shaft and the worm wheel when the rattle mode is recognized; and a clearance compensator for generating a clearance compensating force for compensating the clearance between the worm shaft and the worm wheel in accordance with the rattle reduction control signal, in a direction from the worm shaft to the worm wheel.

    본 발명은 감속기의 유격 보상을 위한 제어기와 감속기의 유격 보상 시스템 및 그 방법에 관한 것으로 감속기의 유격 보상 시스템은 제1샤프트와 연결되어 회전력을 전달받는 웜축, 웜축에 맞물려 제2 사프트에 회전력을 전달하는 웜휠, 토크센서에서 출력된 토크신호에 근거하여 래틀모드를 인식하고, 래틀모드가 인식되면 웜축 및 웜휠 간의 유격에 의해 발생하는 래틀을 저감시키기 위한 래틀저감 제어신호를 출력하는 제어기, 래틀저감 제어신호에 따라 웜축 및 웜휠 간의 유격을 보상하기 위한 유격보상력을 웜축에서 웜휠방향으로 발생시키는 유격보상기를 포함한다.
