The challenges include multi-missile cooperative control and target’s trajectory prediction. A controller based on nonlinear distributed model predictive control (NDMPC) is designed for multiple missiles against a maneuvering target, and a trajectory prediction method based on particle swarm optimization (PSO) algorithm is proposed. This study has mainly completed the following three aspects of work. Firstly, the cost function of the controller is constructed to optimize the accuracy and synchronization of the multi-missile system with consideration of collision avoidance. Secondly, the velocity control of the leading missile is designed by using the range-to-go information in real time to ensure the attack efficiency and the control of the terminal velocity difference. Finally, a kinematic model of the target is estimated by using short-term real-time data with the PSO algorithm. The established model is employed to predict the target trajectory in the interval between radar scans. Numerical simulation results of two different scenarios demonstrate the effectiveness of the proposed cooperative guidance approach. Key words: multiple missiles, nonlinear distributed model predictive control (NDMPC), particle swarm optimization (PSO), trajectory prediction, cooperative guidance CLC number: TJ 765.3 Document code: A
0 Introduction With the development of communication technology, the modern battlefield takes cooperative engagement as the strategic focus. Therefore, the application of cooperation in the missile system has naturally become a research hot topic[1-3] . Cooperatively attacking a highly maneuverable aircraft has been recognized as one of the most difficult tasks in air combat[4-6] . The simultaneous attack, as a classic form of coordinated attacks, can effectively improve the penetration and damage[7-8] . Multi-missile simultaneous attacks are usually carried out in one of the following two ways. The first one is individual control which basically uses the impacttime-control guidance (ITCG)[9-12] . Jeon et al.[13] first proposed a guidance law combining the well-known proportional navigation guidance (PNG) law and the feedback of the impact time error. The ITCG method can be used to guide multiple missiles to hit a stationary target simultaneously at a desirable impact time. In this way, the problem is translated into multiple one-onone missile-target engagements with a predetermined Received date: 2020-05-29 ∗E-mail: zhangxuemiaomiao@163
