Three-dimensional impact angle constrained distributed cooperative guidance law for anti-ship missiles

This paper investigates the problem of distributed co-operative guidance law design for multiple anti-ship missiles in three-dimensional (3-D) space hitting simultaneously same target with considering desired terminal impact angle constraint. To address this issue, formulation including 3-D nonlinear mathematical model description, and communication topology are built firstly. Then consensus variable is constructed using available information can reach under proposed acceleration command along line-of-sight (LOS) which satisfies time However, normal accelerations designed to guarantee convergence LOS angular rate. Furthermore, consider constraints, a nonsingular sliding mode (NTSM) control introduced, finite convergent proposed. The proved by second Lyapunov stability method, numerical simulations also conducted verify its effectiveness. results indicate that cooperative regulate error if connecting longer than required time.
