Fault Tolerant Design in the Earth Observing System Archive
The Archive for the Earth Observing System (EOS) is one of the largest and highest data rate archives in the world. The EOS Archive is referred to as EOS Core System (ECS) and is a multi-site distributed data warehouse of Earth-oriented satellite images and science algorithms/reports. Its data holdings are projected to approach five petabytes by 2002. Each distributed site is referred to as a “...
متن کاملFault tolerant nano-satellite attitude control by adaptive modified nonsingular fast terminal control
In this paper, an adaptive fault tolerant nonlinear control is proposed for attitude tracking problem of satellite with three magnetorquers and one reaction wheel in the presence of inertia uncertainties, external disturbances, and actuator faults. Firstly, sliding surface variable is chosen based on avoiding the singularity of control signal and guaranteeing the convergence of attitude trackin...
متن کاملFault Detection for Satellite Attitude Control System with Computation Constraint
Driven by the satellite’s features such as closed-loop, limited storage space and computing capacity constraint, a fault detection scheme based on the coprime factorization and Youla parameterization is proposed for the on-orbit satellite attitude control system. Based on the SISO dynamic of the satellite in pitch direction and the MIMO one in roll/yaw direction, the residuals equal to ˆ ( ) ...
متن کاملLow Earth Orbit Nano Satellite Electrical Power System Design
The following text shows the requirements for LEO satellite’s EPS design, namely the initial mission assessment, the available power budget, the filtering components sizing, the finalized circuit design and the expected efficiency for optimal operation point. One early assessment was the reliability of the photovoltaic array system in terms of how the cells should be laid out: whether in parall...
متن کاملDesign of Fault Tolerant Flight Control System
The purpose of the paper is to present an approach to detect, isolate and accommodate the sensor or actuator faults using bank of observer and unknown input observers (UIO). Full order observers, reduced order observers, unknown input observers and Kalman Filter are widely used in state estimations [1]. After the estimation of states, fault detection and isolation can be provided by conducting ...
