Guidance law with impact angle and impact time constraints

2019 Chinese Control Conference (CCC), 2019
In the terminal guidance process, in addition to ensure that the missile intercepts target with a small miss distance, achieving the desired impact angle can also improve the lethality of the missile. On the other hand, controlling the impact time can reduce the time for the target to evade interception and achieve the purpose of multi-elastic ...

A nonlinear impact-angle guidance law

International Journal of Intelligent Unmanned Systems, 2017
Purpose The purpose of this paper is to propose a new nonlinear guidance law to satisfy terminal impact-angle constraints against a stationary target in every possible planar surface-to-surface engagement scenario. The proposed guidance scheme is developed based on the geometry of a circular arc trajectory.

Look-Angle-Shaping Guidance Law for Impact Angle and Time Control With Field-of-View Constraint

IEEE Transactions on Aerospace and Electronic Systems, 2020
In this paper, we propose a guidance law that considers the field-of-view (FOV) limitation as well as the impact angle and time constraints. In order to develop the guidance law, we first design a desired look angle that satisfies the FOV limitation and ...

Impact angle control for planar engagements

IEEE Transactions on Aerospace and Electronic Systems, 1999
A new and practical terminal guidance law is presented for impact angle control for two-dimensional active homing engagement scenarios. Impact angle control is required to enhance terminal effectiveness of antitank and antiship missile systems in particular.

Nonlinear Suboptimal Guidance Law With Impact Angle Constraint: An SDRE-Based Approach

IEEE Transactions on Aerospace and Electronic Systems, 2020
In this article, a guidance law with impact angle constraint is developed using the state-dependent Riccati equation (SDRE) technique. First, the nonlinear guidance dynamics consisting of line-of-sight (LOS) angle rate and error is formulated under a ...

Field-of-View Constrained Guidance Law for a Maneuvering Target With Impact Angle Control

IEEE Transactions on Aerospace and Electronic Systems, 2020
Most existing impact angle control guidance (IACG) laws that consider the reduced seeker field-of-view (FOV) focus only on a stationary or a nonmaneuvering moving target.

Neural-Network-Based Nonlinear Optimal Terminal Guidance With Impact Angle Constraints

IEEE Transactions on Aerospace and Electronic Systems
The terminal guidance problem considering nonlinearity, optimality, and impact angle constraints is investigated. First, the conditions for optimal guidance in the longitudinal plane are derived based on the Pontryagin's maximum principle, and then the ...

Impact Time and Angle Control Guidance

AIAA Guidance, Navigation, and Control Conference, 2015
In this paper, a guidance strategy, which extends the existing impact angle control guidance laws to cater to the impact time constraints as well, is proposed. This guidance scheme is based on switching between sliding mode control based impact time control guidance law and the impact angle control guidance laws.
