【摘要】 首先构造带前后缘控制面二元机翼的非定常气动力运动状态方程,利用Lie导数理论对其进行输入/输出局部反馈线性化;然后考虑模型的非定常气动力动气压力参数不确定性,在Lyapnov稳定意义下设计该模型的自适应控制律。仿真结果表明所设计的自适应反馈律能够快速镇定非线性气动弹性翼段的受扰振动,且在作动器输入出现饱和的情况下,仍能对翼段的颤振进行有效控制。更多还原

【Abstract】 An adaptive control method of a nonlinear aeroelastic wing has been studied. First the station space of the nonlinear aeroelastic wing ‘s dynamic equation was formed. Then base on Lie derivative,the partial input/output feedback linearization was obtained. Suppose there is parametric uncertainty for the unsteady aerodynamic press, Lyapunov function was used to design an adaptive control law. Numerical simulations show that this adaptive feedback laws design can quickly stabilize the unstable aeroelastic model with leading-and trailing-edge surfaces, the adaptive feedback laws works even in the situation of the actuator saturation.更多还原
