Flutter control of aeroelasticity with freeplay nonlinearity

  • 摘要: 研究了亚音速不可压来流中二元机翼气动弹性颤振主动控制问题.采用Theodorsen准定常气动力建立俯仰方向含有间隙非线性的气动弹性动态方程,然后基于状态依赖Riccati方程推导了非线性颤振控制律.假设只有俯仰角位移和控制面偏转位移可以直接测量,状态空间中的其它变量通过所设计的状态观测器进行了估计.仿真结果显示,观测器可以快速准确地对非直接测量变量进行估计,系统状态变量与控制变量都能够迅速地收敛于零点,表明所设计的控制律可以有效地实现对间隙非线性二元机翼颤振的抑制.
