Simulation Study on Optimal Control of Flutter Amplitude of Aircraft Wing

对飞机机翼的振颤幅度进行优化控制,能够有效提高飞机飞行的安全性。对机翼振颤幅度优化控制,需要对机翼振颤方程求解,计算出特征值和频率,完成机翼振颤幅度的优化控制。传统方法首先建立动力学模型,分析机翼仰刚度,但忽略了计算特征值和频率,导致控制精度低。提出飞机机翼振颤幅度优化控制方法,分析影响机翼震颤因素,得到机翼的动力学方程,确定机翼振颤方程,对机翼振颤方程求解,计算出特征值和频率,实现对飞机机翼振颤幅度优化控制,仿真实验结果表明,该方法能够有效提高飞机飞行的安全性。

Traditional optimization control method of chattering amplitude of airplane wing always ignores to cal- culate feature value and frequency, which leads to poor control precision. In order to overcome the problem, a new optimization control method is proposed in this article. Factor influencing wing chattering is analyzed. Kinetic equation of wing is obtained. Equation of the wing chattering is determined and solved. Feature vale and frequency are calculated. Thus, the optimization control is achieved. Simulation results reveal that the method can improve security of airplane flight effectively.
