Abstract：The H∞ robust control on a rear-sting wind tunnel model was experimentally studied. Due to that the model is suffering from external disturbance,an Eigensystem Realization Algorithm(ERA) was used for model identification. In order to obtain a stable and robust system,a H∞ hybrid sensitivity optimization controller was designed to suppress the vibration of first two modes of the structure. The results of experiments indicate that the controller based on ERA model identification method is effective for vibration suppressing,and the vibration amplitude of first two modes is reduced to less than 10% compared to uncontrolled state.
