AN ANALYSIS OF COMPENSATION TECHNIQUES AND SENSOR NONLINEARITIES IN A MASS EXPULSION SINGLE-AXIS SATELLITE ATTITUDE CONTROL SYSTEM.

Abstract

The prime objective of the investigation was to analyze compensation techniques and sensor nonlinearities in a mass expulsion attitude control system. Three conventional compensators and combinations of these are analyzed and the results presented and compared for acquisition and limit cycle operation. Based primarily on the criterion of low fuel consumption, the rate gyro compensator is best for acquisition while the pseudo-rate compensator is best for limit cycle. The effects of sensor nonlinearities are analyzed for rate and displacement gyros. The rate gyro deadzone produces the only significant effect on the system. This deadzone considerably increases the fuel consumption in the limit cycle. As an extra objective, a unique compensation technique is derived which greatly decreases fuel consumption during acquisition. (Author)
