Aiming at the attitude elastic tracking control problem of networked spacecraft, drawing on the idea of active anti-jamming control, an attack detection mechanism is designed to monitor the network attack from the controller end to the actuator end, and two adaptive observers are designed by using the network channel to transmit information. Real-time estimation of external disturbances and malicious attack signals while internal noise. A composite anti-jamming and anti-attack controller is designed by combining multiple feedforward and feedback methods to offset the impact of disturbances and attacks on system performance and improve networked spacecraft. system security and stability.
Key words
Spacecraft attitude control, adaptive observer, elastic control, anti-jamming control
