【摘要】 针对高超声速飞行器的纵向非线性动力学模型,将其在某平衡飞行条件下进行线性化,并利用参数依赖Lyapunov函数方法设计了状态反馈控制器,保证了系统的鲁棒稳定性。最后,通过仿真实例验证了控制器设计方法的有效性。
【Abstract】 Model linearization problem is studied for the longitudinal nonlinear dynamics of hypersonic vehicle.Based on parameter-dependent Lyapunov functions,static feedback controller which guarantees the robust tracking performance is designed for the closed-loop system.Finally,the application to numerical example shows the validity of the proposed design approaches.
