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

Sliding mode guidance for impact time and angle constraints

Proceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace Engineering, 2017
This paper proposes a guidance strategy, which caters to both impact angle and impact time terminal constraints. This guidance scheme is based on switching between impact time and impact angle guidance laws. Unlike the existing impact time guidance laws, the proposed guidance strategy takes into account the curvature of the trajectory due to ...

Optimal control based guidance law with impact angle constraint

2017 36th Chinese Control Conference (CCC), 2017
An optimal impact angle control guidance law is proposed in this paper. The missile system is approximated under the small heading error assumption and the impact angle control guidance law is derived based on the approximated system to minimize the energy cost. The proposed guidance law has a form of biased PNG law and it's in accord with the previous

Optimal impact angle guidance law with barrier constraint

Proceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace Engineering
This paper presents an optimal guidance law for missile to achieve desired impact angles on a stationary target while accommodating the barrier constraint. The proposed guidance law consists of two parts: a baseline guidance command for intercepting the target with desired impact angles, and a bias command to prevent collision with the barrier ...

Optimal guidance for guided projectile with impact angle constraint

2018 IEEE CSAA Guidance, Navigation and Control Conference (CGNCC), 2018
To improve the damage effect of guided projectile, not only miss distance is required to be the minimum, but also the projectile is required to attach the target with a specific angle. Since the guided projectile has no seeker and cannot carry on the terminal guidance, it is necessary to achieve a specific terminal attack angle by optimizing the ...

Elliptical Trajectory Guidance Law with Terminal Impact Angle Constraint

AIAA Atmospheric Flight Mechanics Conference, 2015
A guidance law with terminal impact angle constraint is presented, which can guide a missile in accordance with an elliptical trajectory to adapt its maneuverability. For ballistic missiles or reentry vehicles, maneuverability is limited and varies with the flight altitude and speed.

A novel guidance law using integral terminal sliding mode with impact angle constraint

Cybersecurity and Cyberforensics Conference, 2019
The terminal guidance problem for missiles intercepting maneuvering targets with terminal impact angle constraints is investigated. A finite-time impact angle constraint guidance law is developed using the nonsingular integral terminal sliding mode ...

Nonsingular Terminal Sliding Mode Guidance with Impact Angle Constraints

Journal of Guidance, Control, and Dynamics, 2014
Guidance laws based on a conventional sliding mode ensures only asymptotic convergence. However, convergence to the desired impact angle within a finite time is important in most practical guidance applications. These finite time convergent guidance laws suffer from singularity leading to control saturation.

Augmented Polynomial Guidance With Impact Time and Angle Constraints

IEEE Transactions on Aerospace and Electronic Systems, 2013
In this paper, a new impact time and impact angle control guidance law for homing missiles against a stationary target is proposed. To derive a state feedback command for the proposed law with terminal constraints on the impact time and angle, we introduce a polynomial function of the guidance command with three unknown coefficients, one of which is ...
