This paper proposes a cooperative guidance law for attacking a ground target with the impact angle constraint based on the motion camouflage strategy in the line-of-sight(LOS)frame.A dynamic model with the impact angle constraint is established according to the relative motion between multiple missiles and the *** process of cooperative guidance law design is divided into two ***,based on the undirected graph theory,a new finite-time consensus protocol on the LOS direction is derived to guarantee relative distances reach *** the value of acceleration command is positive,which is beneficial for engineering ***,the acceleration command on the normal direction of the LOS is designed based on motion camouflage and finite-time convergence,which can ensure the missiles reach the target with the desired angle and satisfy the motion camouflage *** finitetime stability analysis is proved by the Lyapunov *** simulations for stationary and maneuver targets have demonstrated the effectiveness of the cooperative guidance law proposed.

In order to realize cooperative engagement for multi-missile, a new guidance law based on De Bruijn network is introduced in this paper. Firstly, the theory of network synchronization which is no need to estimate the impact time manually is used to design the guidance law, and the advantage is that the state of all the missiles will converge automatically in a short ***, by adopting De Bruijn network to build the local interactions, the communication network has good fault tolerant property, flexibility and high reliability to ensure information sharing and exchange among missiles. Finally, it is strictly verified by the simulation results that the law can drive all the missiles salvo attack the stationary target simultaneously.

Adaptive Sliding Mode cooperative guidance law against Maneuvering Target

第37届中国控制会议

For the problem of multi-missiles intercept a maneuvering target, an adaptive sliding mode cooperative guidance law is proposed based on both consensus algorithm and adaptive sliding mode method in this paper. Firstly, the time-to-go is introduced as an extra state variable into system dynamics. Considering the system dynamics and consensus algorithm, the ‘integral sliding mode’（ISM） variables including intercept time and light of sight（LOS） angel rate are designed, respectively. Then, the adaptive sliding mode controller is proposed in which the adaptive law can enable the switching magnitude to adapt the external disturbances. It can solve the problem that the switching magnitude can only increase in the conventional adaptive sliding mode method. And the adaptive sliding mode controller can eliminate the external disturbances brought by target maneuvering. The consensus protocols can guarantee the multi-missile intercepting the maneuvering target at the same time, with the LOS angles converge to the desired values and the LOS angle rates converge to zero. Simulation results show that the proposed cooperative guidance law is effective and robust.
