Summary:This article investigates a flexible satellite consisting of a central hub and two flexible solar panels. Different from previous control works, the output time delay is considered in vibration control for the satellite, whose model is more complex and strongly coupled. For dealing with output time delay, a compensated strategy based on a Luenberger observer and a predictor is developed to obtain the estimation of the current state. Then, a predictor-based control law is proposed to eliminate the vibration of flexible solar panels. Finally, the stability of the closed-loop system is analyzed by Lyapunov's direct method, and simulation results are given to demonstrate the efficiency of the developed method.
