进行远程逼近遮蔽干扰时,干扰火箭高度系统所受的干扰主要有弹体参数摄动和海浪干扰,引入模糊滑模变结构控制方法以消除阵风等因素引起的弹体参数摄动,同时在反馈环节引入组合高度测量方法,用于削弱海浪对高度系统的干扰。研究结果表明:基于组合高度测量的模糊滑模变结构控制方法,与传统PID方法相比,具有能够有效抑制干扰火箭掠海飞行时的扰动,提高干扰物布放精度的优点。
For remote approximation of shadowing interference, the disturbance of the interfering rocket height system is mainly perturbed by the projectile parameter and the disturbance of the waves. The fuzzy sliding mode variable structure control method is introduced to eliminate the perturbation of projectile parameters caused by gusts and other factors. At the same time, The introduction of a combination of height measurement methods, to weaken the waves on the high degree of system interference. The results show that the proposed fuzzy sliding mode variable structure control method based on combined height measurement has the advantages of restraining the disturbance of the interfering rocket during the sea sweeping and improving the accuracy of the interfering objects compared with the traditional PID method.
