大气层内拦截弹直接侧向力/气动力混合控制系统设计

Hybrid Control System Design for an Atmospheric Interceptor Controlled by Lateral Jet Thrusters and Aerodynamic Surfaces

研究采用直接侧向力/气动力复合控制方案的大气层内拦截导弹的自动驾驶仪设计问题。考虑直接侧向力的离散工作特性,针对系统中同时存在连续控制量,即舵偏角,和离散控制量,即脉冲发动机反作用力的特点,采取混合控制系统设计方法,先完成舵控连续系统设计,然后完成直接侧向力控制采样控制系统设计。对每一步设计工作进行了稳定性分析,并利用数值仿真验证了设计结果的有效性。

A new auto-pilot design approach is presented for the atmospheric interceptor controlled by the combination of lateral jet thrusters and aerodynamic surfaces.Considering the discrete property of the lateral pulse jet thrusters and the continuous property of the aerodynamic fins,we design a hybrid control system.A continuous closed-loop system with the aerodynamic fin as control variable is first designed.A sampled-data closed-loop control system with the lateral pulse jet thrusters as control variable is th...
