TL;DR: In this article, the authors proposed a finite time convergent guidance law for a homing missile to intercept a maneuvering target. And they proved that the line-of-sight (LOS) angular rate converges to zero in finite time under the proposed guidance law.
Abstract: Taking into consideration both the autopilot dynamics and uncertainties, this paper proposes a finite time convergent guidance law for homing missile to intercept a maneuvering target Firstly, an exact observer (differentiator) is employed to estimate the target maneuvers in finite time Then, a finite time convergent guidance law is designed based on the existing finite time sliding-mode control theory It is proved that the line-of-sight (LOS) angular rate converges to zero in finite time under the proposed guidance law Compared with the existing finite time guidance laws, this guidance law can compensate for the effects of the autopilot dynamics and uncertainties, and the information used for feedback control is much easier to obtain Finally, simulation results show that our scheme, as a finite time convergent algorithm, has strong robustness to bounded disturbances

TL;DR: A robust optimal control method for longitudinal dynamics of missile systems with full-state constraints suffering from mismatched disturbances is developed by using adaptive dynamic programming (ADP) technique to learn an adaptive optimal controller for nominal systems.
Abstract: This paper aims to develop a robust optimal control method for longitudinal dynamics of missile systems with full-state constraints suffering from mismatched disturbances by using adaptive dynamic programming (ADP) technique. First, the constrained states are mapped by smooth functions, thus, the considered systems become nonlinear systems without state constraints subject to unknown approximation error. In order to estimate the unknown disturbances, a nonlinear disturbance observer (NDO) is designed. Based on the output of disturbance observer, an integral sliding mode controller (ISMC) is derived to counteract the effects of disturbances and unknown approximation error, thus ensuring the stability of nonlinear systems. Subsequently, the ADP technique is utilized to learn an adaptive optimal controller for the nominal systems, in which a critic network is constructed with a novel weight update law. By utilizing the Lyapunov's method, the stability of the closed-loop system and the convergence of the estimation weight for critic network are guaranteed. Finally, the feasibility and effectiveness of the proposed controller are demonstrated by using longitudinal dynamics of a missile.

TL;DR: In this paper, a self-propelled missile is mounted on a hand-held launcher and arranged to carry a flotation device in a collapsed condition from the launcher to a distressed target.
Abstract: Rescue apparatus comprising a self-propelled missile mounted on a hand-held launcher and arranged to carry a flotation device in a collapsed condition from the launcher to a distressed target, the launcher and flotation device being connected by a flexible line, so that when the missile is aimed and launched toward the target, the flotation device is carried to the target and then deployed automatically to provide flotation support and establish a "life-line" from the launcher.

TL;DR: In this article, the authors discuss the threat that terrorists with shoulder fired surface-to-air missiles (SAMs), referred to as Man-Portable Air Defense Systems (MANPADS), pose to commercial airliners.
Abstract: Recent events have focused attention on the threat that terrorists with shoulder fired surface-to-air missiles (SAMs), referred to as Man-Portable Air Defense Systems (MANPADS), pose to commercial airliners. This report discusses SAMs and examines options for mitigating missile threats.
