中文摘要:
针对基于分布式通信数据链的多枚侧滑转弯导弹采用领弹-从弹模式协同作战的问题,提出一种协同作战制导控制方法.假设领弹按照比例导引律攻击目标,设定领弹和从弹之间的通信拓扑并设领弹为唯一的根节点,将各导弹的弹目距离作为协调变量,在弹间通信拓扑固定和跳变的情况下,研究了能使各从弹的弹目距离与领弹的弹目距离达到协同一致的一致性协调策略,从而得到各从弹的期望弹目距离.基于反馈线性化方法,并考虑框架角等约束,推导了能够使从弹的实际弹目距离跟踪期望弹目距离的速度前置角指令.综合考虑侧滑转弯导弹的制导与控制问题,建立了其在水平面内运动的制导控制一体化模型,基于滑模动态面控制理论,设计了能够良好跟踪速度前置角指令的鲁棒控制器.仿真结果验证了所提出协同制导控制方法的有效性.
English Summary:
A cooperative guidance and control law was proposed concerning multiple slide-to-turn missiles with decentralized communication attacking the target based on the leader-follower mode. The leader was supposed to attack the target according to proportional navigation guidance law. The reasonable communication topology was set and the leader was set to be the root of the topology, and then the range-to-go of each missile was regarded as a cooperative variable, the consensus cooperative strategy was discussed under the fixed communication topology and changing communication topology, which made the range-to-go of followers consensus with that of the leader. Then the expected range-to-go of followers was obtained from the consensus cooperative strategy. Based on feedback linearization theory and the constraint of missile's gimbal angle, the command of velocity lead angle of missile was deduced to make the follower's actual range-to-go track the expected range-to-go. Considering missile's guidance and control together, the integrated guidance and control model of follower in horizontal plane was established, a robust controller was designed based on the sliding mode dynamic surface theory to track the command of velocity lead angle with high precision. Simulation results proved the validity of the cooperative guidance and control law.
