Experiments in modern control on-board IRAS
Abstract
The paper describes algorithms for on-board commanding, estimation and control of the attitude of maneuvering spacecraft using an on-board computer. Their performance is demonstrated in in-flight experiments with the Infrared Astronomical Satellite. The following items are discussed: (1) on-board commanding of the spacecraft attitude motion; (2) a model following control technique for attitude maneuvering; (3) an estimator for state feedback and disturbance torque compensation; and (4) a Kalman filter for inertial-optical attitude determination and estimation of gyro parameters.
