垂尾抖振响应的鲁棒-FxLMS主动控制试验

Based on the feedback secondary path damping compensation method, the performance of the FxLMS controller is improved by combining the robust controller with the FxLMS algorithm. Aiming at the control problem of the low-order mode buffeting response of the vertical tail model, we design a robust controller to perform feedback damping compensation on the secondary path, establishing subsequently the multi-mode RFxLMS controller. A ground simulation experiment of vertical tail buffeting active control shows that the RFxLMS controller has faster convergence speed and better convergence accuracy compared with FxLMS controller or robust controller, therefore having a better control effect on vertical tail buffeting. A wind tunnel experiment of vertical tail buffeting active control reveals that the RFxLMS controller has a stable control effect and improves the performance of the control system. The RMS value of the acceleration response is reduced by 39.7%-48.1%.
