Aiaa 98-4471 Tracking Rigid Body Motion Using Thrusters and Momentum Wheels
نویسندگان
چکیده
We develop tracking control laws for a rigid spacecraft using both thrusters and momentum wheels. The model studied comprises a rigid body with external thrusters and with N rigid axisymmetric wheels controlled by axial torques. The thruster torques and the axial motor torques are the controls used to track given attitude motions. Specifically, the thruster torques are used to implement the coarse tracking, and the momentum wheels are used to provide the fine control.

Tracking control laws are developed for a rigid spacecraft using both thrusters and momentum wheels. The model studied comprises a rigid body with external thrusters and with rigid axisymmetric wheels controlled by axial torques. Modified Rodrigues parameters (MRPs) are used to describe the kinematics. The thruster torques and the axial motor torques are computed to track given attitude motions...
متن کاملSatellite Attitude Control and Power Tracking with Momentum Wheels
A control law for an Integrated Power/Attitude Control System (IPACS) for a satellite is presented in this paper. Four non-coplanar momentum wheels in a special configuration, and a set of three thrusters are used to implement the torque inputs. The momentum wheels are used as attitude control actuators, as well as an energy storage mechanism, providing power to the spacecraft. In that respect,...

متن کاملSpacecraft Attitude Rate Estimation From Geomagnetic Field Measurements
This paper develops methods for estimating the rotation rate of a spacecraft using only measured magnetic field data. The goal is to provide rate information for use in applications such as de-tumbling, nutation damping, and momentum management without using gyroscopes. Two algorithms are developed, a deterministic algorithm and an extended Kalman filter. Both algorithms employ the magnetic fie...

A control law for an Integrated Power/Attitude Control System (IPACS) for a satellite is presented in this paper. Four or more energy/momentum wheels in an arbitrary non-coplanar configuration and a set of three thrusters are used to implement the torque inputs. The energy/momentum wheels are used as attitude control actuators, as well as an energy storage mechanism, providing power to the spac...
