Abstract
The present invention relates to a servo motor controller for controlling a servo motor having a current limiting unit, and a tuningless nonlinear control method thereof. According to the present invention, the servo motor controller control method for controlling a servo motor including a current limiting unit comprises the steps of: detecting that the limited current is output according to a current command of the current limiting unit; adjusting a disturbance estimation gain of the servo motor controller in response to the output of the limited current; and generating a control input provided from the servo motor controller to the current limiting unit on the basis of the adjusted disturbance estimation gain.
