Title:
METHOD FOR EXTRACTING MAXIMUM GAIN OF SERVO CONTROLLER
Document Type and Number:
WIPO Patent Application WO/2005/013018
Kind Code:
A1
Abstract:
A method for extracting the maximum gain of a servo controller in which generation of a significant vibration or noise is prevented by detecting a vibration in the early stage even if a machine is vibrated by increasing a control gain. The method for extracting the maximum gain of a servo controller for driving a servo motor repeats a processing for applying a simulation disturbance torque to a torque command by a shaking means while increasing the control gain, detecting vibration of a control system by a vibration detecting means (1), and applying the simulation disturbance torque while increasing the control gain until a vibration of a specified level is detected. A control gain at a moment in time when the vibration in excess of a specified level is detected by the vibration detecting means (1) is set as the maximum gain.
