Abstract

During the wind tunnel model aerodynamic test, the slender cantilever model tail support system is susceptible to low-frequency and high-amplitude resonance caused by airflow separation and turbulence, which has a significant impact on test data quality. To effectively suppress the flow-induced vibration response of wind tunnel models, a hybrid control algorithm combining the filtered-x least mean square (FxLMS) algorithm and the linear active disturbance rejection control (LADRC) controller is proposed. Subsequently, the corresponding controller is designed to build a piezoelectric active vibration reduction system, and the active vibration control ground tests of the wind tunnel aerodynamic model are performed. The results show that the proposed hybrid control algorithm fully utilizes the advantages of the FxLMS algorithm and the LADRC controller, as well as having strong anti-disturbance performance, ensuring reliable measurement of the wind tunnel model aerodynamic characteristics.
