Collision-Free Control for Multiple Satellites via Formation Feedback of Virtual Structure

This paper has tried to control for multiple satellite formation flight under a method called Virtual structure. First the algorithm was implemented in the reference coordinate system has no gradient and then we have developed the same algorithm for a circular orbit around the earth within a set of satellites that are in circulation. Then for each of the satellites we have added collision avoidance controller to the system. And then the control system on the satellites such as SPHERES taking into account the constraints operators has control over their implementation.
