摘要

针对垂尾模型低阶模态抖振响应的主动控制问题，设计鲁棒控制器对次级通道进行反馈式阻尼补偿，建立了多模态的RFxLMS控制器，采用宏纤维复合材料压电作动器，开展了垂尾抖振响应压电主动控制的地面模拟试验。试验结果表明，RFxLMS控制器具有收敛速度快、控制效果好的优点，并且相比于单独的FxLMS控制器或鲁棒控制器，对垂尾抖振响应具有更好的控制效果。进一步开展了垂尾抖振响应主动控制的风洞试验。结果表明，RFxLMS控制器在多个试验工况下均有稳定的控制效果，并提升了控制系统的性能，垂尾抖振受控响应的RMS值比无控响应的RMS值降低了39.7%~48.1%。

Abstract

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%.
