Title:
ATTITUDE CONTROL DEVICE FOR FLYING BODY
Document Type and Number:
Japanese Patent JP3189027
Kind Code:
B2
Abstract:

PURPOSE: To attain negating an influence by thrust of a tail rotor and disturbance by obtaining a specific target attitude angle by acceleration and gravitational acceleration in longitudinal and lateral directions, and controlling an airframe so that an airframe attitude angle, obtained by an attitude angle arithmetic device, agrees with this target attitude angle.
CONSTITUTION: Acceleration αX in a longitudinal direction of an airframe is detected by a longitudinal direction use acceleration detecting sensor 11, and acceleration αY in a lateral direction is detected by a lateral direction acceleration detecting sensor 13. Acceleration, detected by each of these acceleration detecting sensors 11, 13, and gravitational acceleration (g) are substituted for θX=αY/g, θY=-αX/g, to obtain target attitude angles θX, θY. An airframe is controlled so that airframe attitude angles θX, θY, obtained by an attitude angle arithmetic device 21, are conformed to these target attitude angles θX, θY. In this way, an influence by thrust of a tail rotor and disturbance can be negated.
