Abstract :
Considering the condition that modern spacecraft are always of large flexible appendages and the fact that the flexible vibration often degrades the control system performance, this paper employs a method that consists of a feed-forward compensator and a closed-loop feedback to fulfill attitude maneuver rapidly with little residual vibration. Including a pulse-width pulse-frequency modulator and a PD controller, the feedback control loop is designed to achieve the desired maneuver; the feed-forward compensator, a multi-mode input shaper based on pade approximation, is designed to eliminate the system residual vibration. Simulation results show that the proposed multi-mode input shaper has shorter time duration and can provide robustness to parameters uncertainty. During maneuvers, the presented control strategy introduces less overshoots and shorter system response time
