Fault tolerant control of attitude dynamics of nanosatellites
2017 8th International Conference on Recent Advances in Space Technologies (RAST), 2017 In this paper, fault-tolerant active control of the rotational motion of the satellite has been applied. Satellite mathematical models are introduced, and the nontraditional Kalman filter is designed with the presented control algorithms. Re-adjustment control procedure has been established taking into account the identified control distribution matrix.
