In this paper, by utilizing fixed-time control technique and a leader-follower scheme, three-dimensional (3-D) cooperative guidance law is developed to tackle impact angle constrained simultaneous arrival problem. Firstly, in the line-of-sight (LOS) direction, command for leader put forward make time error converge zero fixed such that capable of reaching target at prespecified time. Then, each...

The paper proposes a two-dimensional impact time control cooperative guidance law under constant velocity and three-dimensional time-varying velocity, which can both improve the penetration ability combat effectiveness of multi-missile systems adapt to complex variable future warfare. First, more accurate time-to-go estimation method is proposed, based on modified proportional navigational (MPN...

This technical memorandum describes a nonlinear guidance law for a single-missile single-target engagement. The guidance relies on the concepts of Lyapunov stability and backstepping, which are constructive methods in nonlinear control theory. The design of the guidance law allows taking into account the nonlinear relative kinematics between the missile and the target, and ensuring ultimate bou...

The six degree-of-freedom nonlinear model of Boeing707 has been established, using classical control method, gliding beam guidance law, lateral beam guidance law, autoflare guidance law a...

In this paper, after defining pure proportional navigation guidance in the 3-dimensional state from a new point of view, range estimation for passive homing missiles isexplained. Modeling has been performed by using line of sight coordinates with a particulardefinition. To obtain convergent estimates of those state variables involved particularly inrange channel and unavailable from IR trackers...
