In this article, two cooperative guidance schemes with impact angle and time constraints are proposed for multiple missiles cooperatively intercepting a maneuvering target in the presence or absence of leader missile. First, interception constraint is formulated based on relative motion equation between interceptors. Subsequently, design law divided into stages. first stage, finite-time consensus theory super-twisting control algorithm, direction line sight (LOS) derived to so that all can...
Non-terrestrial network (NTN) is a trending topic in the field of communication, as it shows promise for scenarios which terrestrial infrastructure unavailable. Unmanned autonomous intelligent systems (UAISs), physical form artificial intelligence (AI), have gained significant attention from academia and industry. These various applications driving, logistics, area surveillance, medical services. With rapid evolution information communication technology (ICT), 5G beyond-5G enabled numerous...
In this study, a model predictive control (MPC)‐based fault tolerant (FTC) design method for air‐breathing hypersonic vehicles (AHVs) is proposed.

Multi-missile salvo attack requires several missiles the target at same time. Because of this, study time-constrained guidance law is needed. There are two main guide ways: individual homing and cooperative homing. Progress in these ways summarized this paper, some laws under special conditions discussed, too. The advantages disadvantages each analyzed, future research direction proposed.
The dynamics of flexible air-breathing hypersonic vehicles (FAHVs) are nonlinear non-minimum, so the internal FAHVs is unstable. traditional dynamic inversion method unsuitable for control FAHVs.
