Abstract

A modified linear equation of formation is given as the control system model of formation keeping control, which includes the influences of J₂ perturbations. Based on system performance analysis of the control model, a control scheme was proposed which using thrusts without radial direction. Guarantee cost control (GCC) method based on LMI method was introduced to design the sliding surface, then a VSC control law for discrete-time linear system with mismatched uncertainty was given. A numeric simulation was given after a design example for LEO satellite formation to validate the robust of the control algorithm.
