Abstract
Slew maneuver of a flexible space structure is studied in this paper to control both orientation and flextural vibration with using one control input only. The control method uses the concept of wave-absorbing control which is to absorb traveling waves in flexible structure at actuator positions. The wave-absorbing control is applied to suppress the excited vibration of flexible structure during slew maneuver and some significant requirements and limitations for the controller design are presented through analysis of the system using the traveling wave approach. Numerical simulation is used to analyze the performance in the frequency and time domains and satisfactory vibration suppression is shown in the low frequency band. Hardware experiment is also conducted to verify the validity of the numerical simulation and good agreement is shown in its performance of the present control algorithm.
