Trajectory shaping guidance for impact angle control of planetary hopping robots [PDF]

open access: yesFrontiers in Robotics and AI
This paper presents a novel optimal trajectory-shaping control concept for a planetary hopping robot. The hopping robot suffers from uncontrolled in-flight and undesired after-landing motions, leading to a position drift at landing.

Fixed-Time Convergent Guidance Law with Impact Angle Control [PDF]

open access: yesComplexity, 2020
The existing convergence control guidance laws are designed via the Lyapunov asymptotic stability theory or finite-time stability theory. However, guidance law based on the Lyapunov asymptotic stability theory would lead the states to zero only as time ...

Minimum-Data-Driven Guidance for Impact Angle Control

open access: yesAerospace
This paper investigates the impact-angle-control guidance problem for varying-speed flight vehicles with constrained acceleration. A learning-based bias proportional navigation guidance (L-BPN) law is proposed to achieve impact-angle-constrained impact ...

Terminal Impact Angle Control Guidance Law Considering Target Observability

open access: yesAerospace, 2022
The problem of the terminal impact angle control guidance law, considering the target observability for passive guidance with bearing-only measurement, is investigated in this paper. Modified line-of-sight (LOS) angle error dynamics and their closed-loop

Design of Impact Angle Control Guidance Law with Arbitrary Time Convergence [PDF]

open access: yesHangkong bingqi, 2022
Aiming at the problem of impact angle constrained guidance, an arbitrary time convergent impact angle constrained guidance (ATC-IACG) law against the stationary target is designed based on the pure proportion navigation (PPN) guidance law and the ...

Research progress of guidance and control technology for multi-UAVs cooperative attack

open access: yesHangkong gongcheng jinzhan, 2023
The suicide UAV has the characteristics of long-term cruise and high-speed penetration, which can be used for target reconnaissance and attack. In order to give full play to the advantages of cluster attack, it is of great significance to break through ...

Impact angle control of interplanetary shock geoeffectiveness [PDF]

open access: yesJournal of Geophysical Research: Space Physics, 2014
AbstractWe use Open Geospace General Circulation Model global MHD simulations to study the nightside magnetospheric, magnetotail, and ionospheric responses to interplanetary (IP) fast forward shocks. Three cases are presented in this study: two inclined oblique shocks, hereafter IOS‐1 and IOS‐2, where the latter has a Mach number twice stronger than ...

Multi-Constrained Geometric Guidance Law with a Data-Driven Method

open access: yesDrones, 2023
A data-driven geometric guidance method is proposed for the multi-constrained guidance problem of variable-velocity unmanned aerial vehicles (UAVs). Firstly, a two-phase flight trajectory based on a log-aesthetic space curve (LASC) is designed.

Generalized Guidance Formulation for Impact Angle Interception with Physical Constraints

open access: yesAerospace, 2021
This paper proposes an optimal impact angle control guidance law for homing missiles with a narrow field-of-view of the seekers. As groundwork for designing a guidance law, we first present a general guidance structure that can achieve any terminal ...

Unsaturated Optimal Guidance Law for Impact Angle and Acceleration Constraints

open access: yesIEEE Access, 2023
Most research on impact angle control has not addressed acceleration constraints, as it assumes that maneuverability is sufficient. However, when guidance commands are saturated due to aerodynamic or structural loads, the miss distance and impact angle ...
