| 摘 要： | 基于弹体动力学,讨论了防空导弹运动的可控性及其条件。采用以速率陀螺为敏感元件与伺服系统构成的速率反馈回路,以及为适应静不稳定弹体的气动特性引入的具复合反馈的稳定回路,以使弹体的跟踪过程有较佳的动态响应,并分析了两种回路的特性。讨论了导弹非中立稳定、中立稳定等状态的控制,以及控制系统的响应。研究表明：具复合稳定回路控制系统的弹体运动稳定和指令控制的鲁棒性较优。

| Abstract: | The motion controllability and its condition of air defense missile were discussed based on the dynamics of missile body in this paper. The rate feedback loop constructed by rate gyro which was served as sensor unit and servo system, and the stable loop with complex feedback to aerodynamic characteristic of static unstable missile were applied to make a better dynamic response in the tracking period. The features of the two loops were analyzed. The missile control under the state of non-intermediate stability and intermediate stability, and the response of the control system were also discussed. The research showed that the robustness of the stability and command control for the control system with complex stable loop was good. |
