摘要
车载武器沿纵轴和横轴的机动能力受到很大限制,无法作大的角机动,而传统的速度或姿态匹配算法需要载体能作大幅度的机动运动,否则方位失准角的估计效果不理想。针对车载武器系统机动能力受限的现状,特提出"速度+角速度"匹配算法。同时将导弹的起竖过程中作为机动条件,并将主子惯导之间的挠曲变形作为噪声用H∞滤波器进行处理,解决了建模困难的问题。经仿真分析,该方法可以在导弹起竖过程中完成传递对准,对准精度可在90 s起竖过程内达到3'以内。
The flexibility of land-launched missile is greatly restricted. It has difficulty in moving through its axis x and y, so the result of conventional velocity match method of transfer alignment is not so good. To solve the problem of alignment under low dynamical maneuver, velocity plus angular rate match method is proposed. By using the vehicle brake and the launcher uprising, and H∞ filter is used to deduce the flexure as indeterminate interference, the model is built. The simulation results show that this method can finish the alignment process within the uprising procedure and the accuracy can be within 3＇in only 90 seconds.
