Fractional Guidance Law with Impact Angle Constraint and Seeker’s Look Angle Limits

Unmanned Systems, 2023
In this paper, using fractional mathematics, the guidance law of collision angle control is proposed by simultaneously taking into account the limitation of the seeker’s look angle. In order to apply the limitations of impact angle and launch in the equations of the acceleration command, the movement path from the time of launch to reaching the target

Impact-angle-constraint look angle guidance for miniature missile

2016 16th International Conference on Control, Automation and Systems (ICCAS), 2016
An engagement dynamic model is set up for the miniature missile guidance solution under the constraints of field-of-view angle and terminal impact angle. The impact-angle constraint guidance law design is converted into an optimal control problem subjected to terminal constraints.

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 ...

Impact time control guidance law with large impact angle constraint

Proceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace Engineering, 2015
The problem of impact time control with large impact angle constraint is addressed. The dynamics of impact time error under the biased proportional navigation based impact angle control guidance law is first derived for the case of large impact angle constraint.

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 ...

Involute guidance laws with terminal impact angle constraints

2016 IEEE Chinese Guidance, Navigation and Control Conference (CGNCC), 2016
An involute guidance laws with terminal velocity direction constraint have been proposed for terminal maneuver unpowered reentry vehicle. According to the flight characteristics of unpowered vehicles and the geometric properties of the involute of a circle, an involute trajectory was generated by two positions of vehicle and target and an impact angle ...

Integrated guidance and control with impact angle constraint

2017 Chinese Automation Congress (CAC), 2017
In this paper, an adaptive integrated guidance and control(IGC) law is proposed for the missile intercepting the maneuvering target with impact angle constraint. Considering the parameter uncertainties, a new IGC model is established. Subsequently, the dynamic surface control and adaptive technique are combined to design the adaptive IGC law.

Observer-Based Guidance Law With Impact Angle Constraint

Journal of Dynamic Systems, Measurement, and Control, 2017
Accounting for the autopilot as second-order dynamics, an observer-based guidance law with terminal impact angle constraint is designed using the dynamic surface control method. Some first-order low-pass filters are introduced into the designing process to avoid the occurrence of high-order derivatives of the line of sight (LOS) angle in the expression
