摘要: 基于小扰动线性化的纵向弹体控制模型,研究了三回路驾驶仪及其新弹体的结构、快速性、鲁棒性以及对静不稳定弹体的增稳能力,建立并分析了驾驶仪的无量纲模型,针对三回路驾驶仪提出了一种新的设计思路。研究结果表明:阻尼回路新弹体增稳能力和鲁棒性较弱;增稳回路新弹体具有良好的鲁棒性和增稳能力但响应速度较慢;三回路驾驶仪通过设计一个远离开环弹体频率的一阶主导极点和一对阻尼合适的高频极点,使系统具备较好的快速性、稳定性和鲁棒性。

Abstract: Based on the linearized and small perturbation model of the longitudinal missile control system, the configuration, response time, robustness and capability of stabilizing a static unstable missile are studied for the aforementioned systems. A non-dimensional model of the autopilot is established and analyzed, and a new method for the three-loop autopilot design is put forward. The results indicate that thestabilizing loop system is more robust and capable of stabilizing a static unstable missile compared withthe damping loop system,but its response time is longer; while the three-loop autopilot is more robust,and faster than the stabilizing loop system by designing a chief pole at lower frequency and a pair of higher frequency conjugate poles with a appropriate damping ratio.
