Title:
CONTROL SYSTEM, MOTOR CONTROL DEVICE, AND MACHINE LEARNING DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/186574
Kind Code:
A1
Abstract:
The purpose of the invention is to provide a control system capable of suppressing a mechanical resonance of an object to be controlled even when at least one of an object to be held and a held state changes. The control system comprises: a notch filter which applies filtering processing to a command for controlling, through feedback control, a machine tool capable of holding an object to be held; a data acquisition unit (1331) which acquires workpiece information and a held state of the workpiece; and an inference unit (1332) which inputs the workpiece information and the held state acquired by the data acquisition unit (1331) to a learned model for estimating an oscillation frequency of the object from the workpiece information and the held state to estimate the oscillation frequency of the object. The notch filter sets the cutoff frequency to the oscillation frequency estimated by the inference unit (1332).
