Parameter-Varying Modeling and Robust Optimal Control of Morphing Aircraft
以可变弯度的变体飞行器为对象,对其进行变参数建模,研究了变形过程的飞行器特性并设计了鲁棒最优控制器。首先研究了不同弯度变形时的气动参数,拟合出两者的函数关系,然后建立了含弯度参数的变体飞行器非线性动力学模型,并进一步构建了飞行器的线性变参数模型,分析了变形过程中飞行器特性的变化。最后利用鲁棒最优控制的方法,研究了飞行器变形过程的稳定控制问题。仿真结果表明,弯度变形能直接影响飞行器的系统特征;鲁棒最优控制器保证了变形过程的稳定性,并改善了飞行性能。
his paper provides a parameter varying model of a morphing aircraft with camber-varying wings. Robust optimal control, combined with analysis of characteristics in deformation process, is presented for the morphing aircraft. Fist, the function between camber deformation and aerodynamic parameters is built of various cambers. Afterword, the nonlinear aerodynamic model including camber parameters of morphing aircraft is built. After building the linear parameter-varying model of aircraft, the changes of aircraft characteristics in deformation process is analyzed. Last, the stability control issues of aircraft during deformation is investigated by designing a robust optimal controller. Results show that camber deformation can directly affect the system characteristics of the aircraft. Robust optimal controller can ensure the stability of the deformation process and improve the flight performance.
