摘要
潜射运载器在发射前进行精确的传递对准十分重要。然而潜射运载器的传递对准精度会因为潜艇挠曲变形而受到严重影响。为了解决艇体挠曲变形给运载器传递对准精度带来的不利影响,对强跟踪滤波器在潜射运载器动基座传递对准中的应用进行了研究,设计了强跟踪滤波器,仿真结果表明在潜艇具有很小的机动以及考虑艇体挠曲变形的条件下能够较好地估计出从惯导相对主惯导的失准角。由于该方法不必建立艇体挠曲变形的复杂模型,使得解决挠曲变形对传递对准精度影响的问题大大简化了,具有一定的工程意义。
It is very important to achieve accurate transfer alignment for carriers on - berd submarine before they are launched. For the existence of body flexure, transfer alignment accuracy of the carriers on submarine may be seri-ously influenced. To solve this problem properly, the application of strong tracking filter in the transfer alignment of carriers on submarine is studied in this paper. Simulations show that the estimate of misalignment of slave navigation system can reach demanded accuracy, without estimating the body flexure angle, even though the maneuver intensity of the submarine is soft and body flexure of the submarine is taken into account. The application of this approach makes the problem simpler without building complex model of body flexure and also shows a feasible method in practice.
