Integrated guidance and control of interceptors with impact angle constraint against a high-speed maneuvering target

Proceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace Engineering, 2019
An integrated guidance and control method is investigated for interceptors with impact angle constraint against a high-speed maneuvering target. Firstly, a new control-oriented model with impact angle constraint of the integrated guidance and control ...

Frontal Offset and Angled Impact Passive Protection

SAE Technical Paper Series, 1993
Occupant protection in offset and strongly angled frontal impacts represents a crash mode in which a significant number of severe and fatal injuries occur each year in the United States. To date, no United States auto manufacturers have acknowledged dealing with or addressing the problem.

A Backstepping-Based Guidance Law for an Exoatmospheric Missile With Impact Angle Constraint

IEEE Transactions on Aerospace and Electronic Systems, 2019
A novel method of exoatmospheric guidance law design is proposed in this paper. By analyzing the nonlinear kinematic equations, a class of nominal motions that requires no maneuver effort can be derived for a nose jet control missile. A unique time to go

Impact Angle Constrained Interception of Stationary Targets

Journal of Guidance, Control, and Dynamics, 2008
In Many advanced guidance applications [1–5], it is required to intercept the target from a particular direction, that is, achieve a certain impact angle.

Limbus impact on off-angle iris degradation

2013 International Conference on Biometrics (ICB), 2013
The accuracy of iris recognition depends on the quality of data capture and is negatively affected by several factors such as angle, occlusion, and dilation. Off-angle iris recognition is a new research focus in biometrics that tries to address several issues including corneal refraction, complex 3D iris texture, and blur.

Observer-Based PIGC for Missiles With Impact Angle Constraint

IEEE Transactions on Aerospace and Electronic Systems, 2019
In this paper, we present an observer-based partial integrated guidance and control (PIGC) scheme for missiles to achieve hit-to-kill attack at a given impact angle.

Successful High Angle Completions, Cementing, and Drilling's Impact

Proceedings of International Meeting on Petroleum Engineering, 1988
ABSTRACTSuccessful well completions are the key to exploiting the potential benefits of high angle/horizontal drilling. Successful primary cementing is vital to completion success. Cementing success is often jeopardized by the wellbore created during the drilling process. This paper unfolds this dilemma and takes a look at what must be done to overcome
