PID and Pole Placement Controller for Circular Flying Formation Satellite System

摘要

Currently the study of formation flying systems (FFS) and the control of satellite formation flying in circular orbit are becoming increasing important. In this paper we analyse the circular orbit flying formation of a micro-satellite to assess its stability and control using pole placement, we then add a PID controller and a suitable actuator in order to decrease overshoot, improve steady state error response and settling time while optimizing transients to bring the satellite back into the ideal orbit. Simulation based design was carried out for a PID and pole placement controller for a satellite in circular earth orbit under inverse square gravitation using MATLAB software.
