Title:
ROTATION CONTROL DEVICE, MOBILE BODY AND CONVEYANCE ROBOT
Document Type and Number:
WIPO Patent Application WO/2019/111671
Kind Code:
A1
Abstract:
[Problem] To provide a rotation control device which can suppress distortion in orientation and movement even when disturbances occur in rotating body control, and to provide a mobile body and a conveyance robot. [Solution] This rotation control device is provided with a first controller for controlling the rotation speed of a first rotating body to a target first rotation speed, and a second controller for controlling the rotation speed of a second rotating body to a target second rotation speed, and selectively implements a first mode, in which the first controller acquires a first measurement value of the rotation state of the first rotating body and a second measurement value of the rotation state of the second rotating body, calculates correction control such that the relative relation between the first measured value and the second measured value approaches a target relative relation, and applies the aforementioned correction control to the first rotating body, and a second mode, in which the second controller acquires a first measurement value of the rotation state of the first rotating body and a second measurement value of the rotation state of the second rotating body and applies the aforementioned correction control to the second rotating body.
