Robust adaptive control of the spacecraft formation flying in elliptical orbit with high eccentricity

In this paper, the issue of adaptive robust control of the spacecraft formation flying will be discussed. For this purpose two high order sliding mode controller (HOSMC) are designed for nonlinear spacecraft formation flying in leader-follower structure considering actuator saturation. The SMC- super twisting algorithm is applied due to chattering reduction and so SMC-nonsingular terminal is applied due to finite time convergence.
in designing both controllers, the actuator saturation is considered.
To reduce the control effort, the adaptive gains are applied. The gains of super twisting controller are adapted due to the response error. Both adaptive super twisting and terminal sliding mode are proposed on the PROBA-3 Space mission. The controllers’ performances are examined in formation flying maneuvers with large eccentricity considering J2 disturbance effects.
