Abstract :
The controlled spacecraft with a retractable flexible appendage may be unstable during retraction of appendage because of the improper rate of retraction designed. In this paper, according to the Lyapunov second method, the sufficient conditions which guarantee the stability of the system controlled by the PD law in retracting phase are deduced. These conditions are instructive for designing the proper rate of retraction and control law to satisfy the stabilization requirement of this system.
