摘　　要：结合传递矩阵在线识别与最优控制理论,构建了一种智能旋翼振动载荷频域高阶谐波控制方法,据此对主动后缘襟翼(ACF)型智能旋翼进行了振动主动控制仿真,重点分析了控制算法的鲁棒性以及算法参数对控制效果的影响。结果表明,在稳态飞行条件下,频率为NΩ的旋翼振动载荷最高降低90%以上;当控制过程中出现旋翼工况改变,控制器仍能保持良好的控制效果。对控制参数选取、数据无量纲处理等方法进行了总结,对智能旋翼振动闭环控制试验设计有一定的指导意义。A higher harmonic control approach to smart rotor vibration reduction was proposed through the combination of on-line identification and optimal control.Based on this approach,active control simulation to a ACF smart rotor was conducted.The robustness of control algorithm and the influence of parameters on control effect were analyzed.The results indicated that the reduction of NΩ hub loads reaching up to 90%.When the working state of the rotor changes,the performance of the controller still going well.The methods of normalization and control parameters selection were summarized,which could be used as a guideline for the closed-loop experiments of smart rotors.
