存在网络丢包的导弹制导控制一体化设计

Integrated guidance and control design for a class of missile with networked packet dropouts

研究了网络环境下存在丢包的导弹制导控制一体化设计问题.多个地面雷达同时对目标进行观测,并通过网络将目标信息传输给导弹.考虑网络存在丢包的情况,将丢包描述为导弹与雷达之间的通信拓扑模型,建立了包含3个级联子系统的导弹纵向通道制导控制一体化模型.将滑模控制与反演控制相结合,给出了每个子系统的虚拟控制量,并设计滤波器对虚拟控制量进行滤波,使得系统对丢包具有一定的鲁棒性.在此基础上,设计导弹制导控制一体化滑模反演控制律,并给出了系统有界输入有界输出(BIBO,Bounded-Input BoundedOutput)稳定的充分条件.数值仿真验证了所提方法的有效性.

An integrated guidance and control（ IGC） algorithm for a class of missile with networked packet dropouts was researched. Considering that a number of ground-based radars were used to observe on the target simultaneously and the target information was shared with the missile through the network. Networked packet dropouts were described as the communication topology model between the missile and radars. The pitch channel IGC model including three cascaded subsystems was established. In this way,virtual controllers were designed for each subsystem. To guarantee the stability of the missile when packets dropouts occur,the corresponding filters were designed for the virtual controllers. An IGC algorithm was put forward by adopting sliding-mode control and back stepping control method. Sufficient condition to guarantee the bounded-input bounded-output（ BIBO） stability of the system was simultaneously derived. Finally,simulation results demonstrate the effectiveness of the proposed method.
