Finite Time Convergence Cooperative Guidance Law for Non-maneuvering Moving Targets

A consensus theory-based distributed cooperative guidance law is proposed for multi-missile intercepting a non-maneuvering moving target in this paper. The model is built on the three-dimensional plane. The designed control method consists of three parts: the part along the line of sight (LOS) guarantees salvo attacks of all missiles, the other two part perpendicular to the LOS in vertical and lateral plane ensure the zero LOS angular rates to achieve accurate interceptions. By applying the Lyapunov stability theorem, convergences of all missiles¶ time-to-go (TGO) are verified. Digital simulations prove the accuracy of the designed multi-missile cooperative control method.
