Document Type and Number:
WIPO Patent Application WO/2020/087354
Kind Code:
A1
Abstract:
Disclosed is a control method for a vertical stability augmentation mechanism (20). The vertical stability augmentation mechanism (20) is used to drive a load (30) to move relative to a base (10) between the upper spacing and the lower spacing of the vertical stability augmentation mechanism (20). The control method comprises: (S1) acquiring a first desired attitude and an actual attitude of the vertical stability augmentation mechanism (20); (S2) when the first desired attitude is located between the upper spacing and an upper preset attitude or between the lower spacing and a lower preset attitude, correcting the first desired attitude to a second desired attitude, and controlling, according to the second desired attitude and the actual attitude, the vertical stability augmentation mechanism (20) to rotate such that the vertical stability augmentation mechanism (20) reaches the second desired attitude; and (S3) when the first desired attitude is located between the upper preset attitude and the lower preset attitude, controlling, according to the first desired attitude and the actual attitude, the vertical stability augmentation mechanism (20) to rotate such that the vertical stability augmentation mechanism (20) reaches the first desired attitude. Further disclosed are a vertical stability augmentation mechanism (20) and a movable device (100).
