Study on project trajectory of air-to-ground missile with strapdown seeker under multi constraints
Xibei Gongye Daxue Xuebao, 2021 The air-to-ground missile with strapdown seeker may have the problems, including small field of view(FOV), limited overload, and fall angle constraint. To solve the above mentioned problem, a phased guidance scheme is proposed. In this scheme, the attack

Dirac constraints in field theory and exterior differential systems [PDF]
, 2010 The usual treatment of a (first order) classical field theory such as electromagnetism has a little drawback: It has a primary constraint submanifold that arise from the fact that the dynamics is governed by the antisymmetric part of the jet variables ...

Visual Tracking in Wind with Field of View Constraints
International Journal of Micro Air Vehicles, 2011 This paper addresses the problem of tracking a ground-based target with a fixed camera pointing out the wing of a micro air vehicle that is subjected to constant wind. Rather than planning explicit trajectories for the vehicle, a nonlinear image-based feedback guidance strategy is developed that maintains the target in the field-of-view of the camera.

IEEE Access, 2020 A prerequisite for implementing precision strike is to keep the target locked within the seeker’s field-of-view (FOV). To address this constraint, a novel impact angle control guidance law based on the dynamic surface control and time-varying ...

Two Higgs doublet dynamics at the electroweak phase transition: a non-perturbative study [PDF]
, 2000 Using a three-dimensional (3d) effective field theory and non-perturbative lattice simulations, we study the MSSM electroweak phase transition with two dynamical Higgs doublets.

AGPC-SLAM: Absolute Ground Plane Constrained 3D Lidar SLAM
Navigation, 2022 3D lidar-based simultaneous localization and mapping (SLAM) is a well-recognized solution for mapping and localization applications. However, the typical 3D lidar sensor (e.g., Velodyne HDL-32E) only provides a very limited field of view vertically. As a

Decentralized Connectivity Maintenance for Quadrotor UAVs with Field of View Constraints
2023 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2023 We present a decentralized connectivitymaintenance algorithm for controlling a group of quadrotor UAVs with limited field of view (FOV) and not sharing a common reference frame for collectively expressing measurements and commands. This is in contrast to the vast majority of previous works on this topic which, instead, make the (simplifying ...

Solving q-Virasoro constraints
, 2020 We show how q-Virasoro constraints can be derived for a large class of (q,t)-deformed eigenvalue matrix models by an elementary trick of inserting certain q-difference operators under the integral, in complete analogy with full-derivative insertions for ...
