Optimal Ground-to-Air Interception with Time-Varying Acceleration Bounds
Or Nahum, Vitaly Shaferman
This paper proposes novel optimal-control-based guidance laws for ground-to-air missiles with time-varying acceleration bounds. In such engagements, as the missile climbs in altitu…
Low-Thrust Orbital Differential Games with Speed Constraint Enforcement Using Cost Weighting
Yahli Drucker, Vitaly Shaferman
This paper considers the problem of a low-thrust spacecraft pursuit-evasion differential game with an arbitrary terminal relative speed constraint. It addresses the terminal phase…
Optimal Powered Descent Guidance with Pyramid-Shaped Approach-Angle Constraints
Revital Frenkel, Vitaly Shaferman
In this paper, a novel optimal soft-landing guidance law with inequality approach-angle path constraints is analytically derived. The proposed guidance law prevents ground collisio…
Optimal Bounded Thrust Powered Descent with Analytical Ground-Collision Avoidance
Or Nataf, Vitaly Shaferman
The paper proposes a new approach to address the bounded-thrust powered-descent problem while ensuring ground-collision avoidance. A time-dependent polynomial approximation of the…
Flyby Distance Pursuit for Guarding a Target with an Inferior Guard
Navot Israeli, Vitaly Shaferman, Oded Golan
Guarding a target against a fast Attacker with a slower Guard is posed as a differential game. Both players follow nonlinear, thrust-free, aerodynamic motion in the plane. The capt…
