Lyapunov-Based Impact Time Control Guidance Law Against Maneuvering Target
Abstract
Nonlinear guidance law that consider impact time constraints are proposed. An impact time control problem has been considered in the two-dimensional environment using Lyapunov stability theory, and the law was expressed in very simple forms to be implemented easily. Under the consideration of the nonlinear kinematics, it is shown that the missile states converge to the desired equilibrium point by the Lyapunov stability theory. The singularity issue of the proposed guidance law is also analyzed. Numerical simulations are performed to verify the performance of the proposed guidance laws. The proposed ITCG laws can be used for the salvo attack of multiple missiles to provide effective results.
