| 摘 要： | 为了尽可能提高导弹机动能力,提出了"大过载采用BTT(bank-to-turn)控制,小过载采用STT(skid-to-turn)控制"的设计原则,由BTT/STT决策模块和双回路控制器组成混合型BTT/STT大攻角导弹自动驾驶仪。采用攻角控制替代了传统的过载控制,推导出将过载指令转换为对应STT(或BTT)控制方法的攻角、侧滑角和滚转角指令的BTT/STT决策算法,由角度变化的长周期运动和转动角速度变化的短周期运动组成一个双回路控制器。针对Backstepping设计方法适合于级联系统稳定控制的特点,采用直接构造Backstepping法来设计双回路控制器。仿真结果表明:该大攻角自动驾驶仪能够满足近距格斗导弹的技术要求。

| Abstract: | Missile maneuverability can be improved with bank-to-turn(BTT) control for large loads and skid-to-turn(STT) control for small loads.A hybrid BTT/STT high angle-of-attack missile autopilot was designed using a BTT/STT decision module and a two-loop controller.The angle-of-attack is used instead of the load as the controller input in the BTT/STT decision algorithm which changes the load response into an angle response for the angle-of-attack,angle-of-slide and roll angle corresponding to the STT or BTT modes... |
