Title:
MOTION CONTROL DEVICE, MOTION CONTROL METHOD, NON-TRANSITORY COMPUTER-READABLE MEDIUM, AND MOTION CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/049809
Kind Code:
A1
Abstract:
Provided is a motion control device that can track movement of a control object on a target trajectory smoothly. This motion control device (100) that performs tracking control of the control object on the target trajectory comprises: a position acquisition unit (101) that acquires the current position of the control object; and a target-trajectory-generating unit (102) that generates the target trajectory from the current position to the final position reached by the control object. The device (100) comprises: a moving-speed-determining unit (103) that determines the moving speed at which the control object moves at each position on the target trajectory; and a control-target-position-calculating unit (104) that sets the control target position in a travel direction on a tangent vector of the target trajectory in the current position to perform feedback control to track the target trajectory of the control object by the moving speed. The control-input-calculating unit (105) calculates the control input to the control object by feedback control that uses the control target position as a target value.
