导弹伪攻角反馈三回路驾驶仪设计分析

阐述了几种典型过载驾驶仪的结构演变过程,对传统三回路驾驶仪的结构进行了适当改进，提出了采用伪攻角作为反馈信号的三回路驾驶仪新结构。研究了驾驶仪工程指标与闭环极点之间的对应关系以及从状态反馈到输出反馈的变换技术，给出了基于输出反馈极点配置的伪攻角反馈三回路驾驶仪设计方法。研究结果表明，伪攻角反馈三回路驾驶仪消除了传统三回路驾驶仪的静差，并具有与其相似的控制特性以及鲁棒性能。分析结果显示，两种结构的三回路驾驶仪对静不稳定弹都具有较好的稳定控制性。

Design and analysis of missile three-loop autopilot with pseudo-angle of attack feedback

For several classical acceleration autopilots,the topologies evolvement is presented firstly.To improve the performance of classical three-loop autopilot,a new three-loop autopilot with pseudo-angle of attack feedback is proposed.The relation between engineering index and closed system poles and the transform technology from state feedback into output feedback are discussed,and a general design method for the new three-loop topology autopilot based on the output feedback pole assignment is proposed.It is concluded that the new three-loop autopilot can eliminate the static error of the classical three-loop topology and has some similarities of the control characteristics and robustness.Both of the new and classical three-loop autopilots can stabilize a static unstable missile very well.
