A novel attitude control method with good rapidity and stability of non-stationary satellite antenna

A novel attitude control method of non-stationary satellite antenna based on a novel non-smooth controller with good rapidity and strong disturbance rejection ability is studied. Firstly a novel non-smooth controller of the standard second order integrator system with a bounded disturbance is studied, its stability within a finite-time is proved by Lyapunov stable theorem and its strong disturbance rejection ability is studied by simulation experiment. The attitude controller of a non-stationary satellite antenna based on the novel non-smooth controller is designed and applied to track the target satellite. Experiments validate the non-smooth attitude controller of a non-stationary antenna could track the target satellite rapidly and stablely and ensure the communication between the non-stationary antenna and the target with high quality.
