Title:
ATTITIUDE CONTROLLER FOR ARTIFICIAL SATELITE
Document Type and Number:
Japanese Patent JPH03220099
Kind Code:
A
Abstract:

PURPOSE: To surely realize the attitude control with high presision and economize fuel consumption by installing a gain adjusting means for setting the gain for the attitude angle signal to α-times and setting the gain for the rate signal to α1/2-times and setting α in variable manner according to the faculty of a driving part and the ON/OFF-interval.

CONSTITUTION: Gain adjusting means 12 and 13 control the gain for the attitude angle signal and the gain for the rate signal in variable manner selectively to α-times or α1/2-times on the basis of the faculty of a driving part 19 and the ON/OFF-interval control information. Accordingly, each of the thrust and attitude control precision of the driving part 19 is set in variable manner. Accordingly, if the fuculty of the thrust of the driving part 19 deteriorates, the gain is adjusted in variable manner so that the thrust is increased, and the reduction of precision is prevented, keeping the desired attitude control precision, and when the reduction of the attitude control precision is allowed, the gain is set in variable manner so that the ON/OFF internal of the driving part is prolonged, and the attitude control precision is reduced, and the fuel consumption is economized.
