Title:
DEVICE, METHOD AND PROGRAM FOR AUTOMATIC POSTURE CONTROL
Document Type and Number:
Japanese Patent JP2007261414
Kind Code:
A
Abstract:

To provide a device, a method and a program for automatic posture control which are rapidly responsive to an abrupt change of the thrust, the disturbance of a gust or the like, and capable of reliably controlling the posture of an airframe even when the air speed is insufficient.

A control unit 9 acquires information on the present position of the center of gravity from a storage unit 11, detects the present rotational speed of a thrust motor 21; calculates adequate information on the position of the center of gravity corresponding to the present rotational speed based on the relationship between the rotational speed of the thrust motor 21 corresponding to the known thrust and the adequate position of the center of gravity corresponding to an adequate pitch angle; obtains the necessary displacement of a battery 26 along the longitudinal direction based on the adequate position of the center of gravity and the present position of the center of gravity; obtains the rotation of the motor for fluctuation of the corresponding position of the center of gravity; and gives the control signal corresponding to the required rotation to a motor drive unit 19.
