摘要
为提高导弹低空飞行时高度控制系统的性能,根据所建数学模型的特点,设计了一种基于反步法的输出控制器,利用Lyapunov理论对系统的稳定性进行了分析,并通过对导弹纵向通道的数字仿真,验证了控制算法的有效性和系统跟踪指令的精确性。
An output controller based on backstepping is designed in this paper to improve the capacity of altitude control system during the missle's low altitude flight. The control method is proposed on the characteristics of the missile altitude model, using Lyapunov theory to guarantee the system stability. The longitudinal model of missile is used in the simulation. Simulation results show the expected efficiency and tracking accuracy of the strategy.
