Adjustable impact-time-control guidance law against non-maneuvering target under limited field of view

Proceedings of the Institution of Mechanical Engineers. Part G, Journal of Aerospace Engineering, 2021
This article proposes an impact-time-control guidance law that can keep a non-maneuvering moving target in the seeker’s field of view (FOV). For a moving target, the missile calculates a predicted intercept point (PIP), designates the PIP as a new ...

Generalized Time-to-Go Inversion Guidance with Impact Time and Angle Constraints

Journal of Guidance Control and Dynamics
A major challenge in homing guidance is that accurately predicting the time to go for missiles is generally difficult, which limits the practical application of a certain class of guidance laws with impact-time constraints or cooperative capabilities. To

Sliding mode–based simultaneous control of impact angle and impact time

Proceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace Engineering, 2021
In this article, a sliding mode control–based nonlinear guidance scheme for controlling both impact angle and impact time simultaneously is proposed. The problem of impact angle control is first transformed to that of controlling line-of-sight angle and ...

Four-Stage Guidance Law for Impact Time and Angle Control Based on the Bezier Curve

IEEE Transactions on Aerospace and Electronic Systems
The impact-time-angle-control guidance (ITACG) law can control the impact time and angle in a wide range of applications. The previous ITACG research generally suffer from the accuracy under the time-varying velocity condition, or the axial acceleration ...

Nonsingular impact time guidance and control using deviated pursuit

, 2021
This paper deals with nonsingular guidance and control design for an interceptor, using a decoupled approach, steered by the combined effects of both canard and tail, to intercept a moving but non-maneuvering target at a time specified a priori.

Impact analysis for timing requirements on real-time systems

2014 IEEE 20th International Conference on Embedded and Real-Time Computing Systems and Applications, 2014
The analysis of real-time properties is crucial in safety critical areas, and is particularly difficult for distributed systems as complex interferences between tasks of different priorities can occur. In previous works we have introduced a state-based analysis approach to validate end-to-end deadlines for distributed systems, where the state spaces of

Optimal control based guidance law to control both impact time and impact angle

Aerospace Science and Technology, 2019
A new guidance law with both impact time and impact angle constraints is proposed in this paper. We first simplify missile dynamics under small heading error approximation, and derive an optimal guidance law with impact angle constraint against a ...
