Title:
MOTION PROFILE GENERATING APPARATUS FOR RESIDUAL VIBRATION REDUCTION
Document Type and Number:
WIPO Patent Application WO/2020/017749
Kind Code:
A1
Abstract:
The present invention relates to a motion profile generation apparatus comprising: an input and output unit for receiving a vibration signal from a vibration sensor that detects the motion of a target object; a signal processing circuit for performing noise filtering and amplification processing on the received vibration signal; a digital oscilloscope module for sampling an output signal of the signal processing circuit per measurement unit time; a display module; a memory in which a motion profile generation program is stored; and a processor for executing the motion profile generation program. According to the execution of the motion profile generation program, the processor outputs a user interface through the display module, receives, from a user through the user interface, inputs of information about the type of a motion controller, information about the type of an input shaper, and configuration parameters for a motion profile, configures a reference motion profile according to the inputs of the user, operates the target object on the basis of the reference motion profile, calculates, on the basis of the vibration signal generated by the target object, a natural frequency and a damping ratio per measurement unit time from data sampled by the digital oscilloscope module, generates an updated input shaper by applying the calculated natural frequency and damping ratio to the input shaper selected by the user, and generates an updated motion profile by applying the updated input shaper to the reference motion profile.
