Robust Decentralized Control of Large Flexible Structures

摘要

This report studies the problem of controlling large flexible structures with robust decentralized feedback control. A decentralized optimal control algorithm is applied to compute the parameters of the robust controller. The proposed method is tested on the ACOSS Model No. 2, which is a realistic evaluation model for active structure control methods. Twelve co-located sensors and actuators are applied in order to suppress vibrations which are caused by two external disturbances. It is demonstrated that the proposed method can stabilize the closed-loop system via decentralized feedback. Other performance measures are also discussed. 11 refs., 8 figs. (ERA citation 13:018865)
