Title:
METHOD FOR CONTROLLING POSTURE OF SPACE FLYING BODY
Document Type and Number:
Japanese Patent JPH03176704
Kind Code:
A
Abstract:
PURPOSE:To attain highly accurate posture control against large disturbance by forming a correction signal based upon a comparator for comparing a sensor output estimating signal with a sensor output. CONSTITUTION:The output estimation signal of a posture sensor model 8 is compared with the output of a practical posture sensor 1 by a comparator 9 and the output of the comparator 9 is inputted to a correction signal calculating part 10, which outputs a signal for correcting a posture sensor output forecasting signal so that a difference between the output of the sensor 1 and an estimation signal goes to zero. An adder 11 adds a correction signal to a posture sensor output forecasting signal to form a posture estimation signal. The output of the comparator 9 is fed back to a space flying body dynamic model 6 when necessary to prevent a posture sensor output forecasting signal from being drifted to one direction.
