TL;DR: Interceptor using norm differential game guidance laws is able to pursue the spacecraft without being intercepted by defender, even though the maneuverability of both interceptor and protector is lower than defender.
26 citations
TL;DR: A class of optimal guidance schemes are proposed based on linear quadratic differential game method and numerical solution of Riccati differential equation to drive the interceptor to the target and away from the defender simultaneously.

TL;DR: Comparison simulations demonstrate that employing multiple feature measurement provides superior estimation performance than methods with less feature measurement, and shows that by using EKF or UKF technique, the relative translation and rotation estimation errors converge rapidly with the desired high estimation accuracy.
Abstract: This paper develops a relative state estimation method for two spacecraft based on monocular vision measurement, where the leader spacecraft of three-dimensional shape is observed by a calibrated c...

TL;DR: A three-dimensional robust nonlinear cooperative guidance law for multiple missiles to simultaneously attack a maneuvering target at desired impact angles is proposed and the fixed-time stability is proved through the Lyapunov theory and bi-homogenous property.

TL;DR: The projection technique and conjugate gradient method are combined to obtain the control that can satisfy the terminal constraints, and a new step-size adjustment strategy is applied to make the algorithm converge faster.

TL;DR: A novel sequential convex programming method based on customized adaptive mesh refinement that can decrease the number of mesh points while ensuring the feasibility of converged solution and an unconventional convergence condition is proposed.

TL;DR: It is proved that the modified solution of the multi-agent differential game of the nominal model achieves quasi-optimality, and it is shown that L 2 -bounded consensus error can be achieved, if the control of the leader deviates from its quasi-optimal strategy.

TL;DR: A novel trajectory optimization method that is achieved with a complete 6-DOF dynamic model of the parafoil delivery system, which has much better realizability and is more consistent with reality.
