弹载捷联天线稳定平台控制与仿真研究

研究了弹载捷联末制导系统中天线稳定控制平台的基本原理和方法,并分别针对导引头天线的纯稳定和目标跟踪两种不同工作模式,提出了相应的数学稳定控制算法,研究了捷联稳定方案下目标视线角和目标视线角速度信息的提取方法,提出了一种纯数学解算的制导信息估算方法。与基于非线性滤波的机动目标跟踪算法相比,本文提出的方法不需要弹目相对距离和速度信息,计算量小、实时性强,但估算精度受传感器噪声影响较大,最后通过一系列数学仿真初步验证了上述方法的有效性。

Study on the Control and Simulation of Missile-borne Antenna Strap-down Stabilization Platform

Mainly discusses basic principals and control techniques of the antenna stabilization platform of a missile-borne strap-down terminal guidance system.Two mathematical stabilization control schemes are proposed respectively to two antenna working modes: one is pure stabilization mode and the other target tracking mode.Studies are mode on target information estimation method in the strap-down stable platform,which results in a novel estimation method both of LOS and of LOS rate.Compared to traditional evaluat...
