Reconfigurability Analysis for Satellite Attitude Control System

摘要

Reconfigurability represents the potential of the system to tolerate faults under resources constraints. This paper provides an approach to evaluate and analyze the reconfigurability of satellite attitude control system (ACS) with respect to actuator faults under a certain configuration. The common configurations of ACS are presented. And the controllability and energy consumption of control are analyzed. Then the smallest eigenvalue of controllability Gramian is utilized to measure the level of reconfigurability. Simulation results are given to demonstrate the effectiveness of the proposed approach.
