Title:
サーボ制御装置
Document Type and Number:
Japanese Patent JP6426770
Kind Code:
B2
Abstract:
A servo controller includes a speed command creation unit, a torque command creation unit, a speed detection unit, a speed control loop, a speed control gain, a sinusoidal disturbance input unit, an actual frequency characteristics calculation unit, a reference characteristics changing unit, a reference frequency characteristics calculation unit, and a control gain adjustment unit. The sinusoidal disturbance input unit changes a frequency sequentially, a reference frequency characteristics calculation unit calculates reference frequency characteristics for characteristics designated by the reference characteristics changing unit sequentially for respective frequencies, the actual frequency characteristics calculation unit calculates actual frequency characteristics of a control system sequentially for respective frequencies, and the reference frequency characteristics calculation unit stores a characteristic formula of the reference characteristics changing unit when the reference frequency characteristics and the actual frequency characteristics match most closely.
