Optimal Guidance Law for Impact Angle Control

IFAC Proceedings Volumes, 2004
Abstract In this paper, a set of optimal guidance laws to achieve zero a miss distance as well as a desired impact angle is presented. Each of optimal impact angle control guidance laws is the solution of a linear quadratic optimal control problem in consideration of proper time-varying weighting function into the cost function.

Quaternion Based Three-Dimensional Impact Angle Control Guidance Law

IEEE Transactions on Aerospace and Electronic Systems, 2021
This article deals with a guidance law for impact angle control (IAC) in the 3-D space. Extended from the 2-D IAC law, the proposed guidance law is derived using a quaternion. The general form of the IAC law comprises a biased proportional navigation guidance (PNG) law, wherein a component to control the impact angle is added to the PNG law.

Impact Time and Angle Guidance With Sliding Mode Control

IEEE Transactions on Control Systems Technology, 2009
A novel sliding mode-based impact time and angle guidance law for engaging a modern warfare ship is presented in this paper. In order to satisfy the impact time and angle constraints, a line-of-sight rate shaping process is introduced. This shaping process results in a tuning parameter that can be used to create a line-of-sight rate profile to satisfy ...

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.

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

Aerospace Science and Technology, 2019
Abstract 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 stationary target.

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.

Control of Impact Angle Using Biased Proportional Navigation

AIAA Guidance, Navigation, and Control (GNC) Conference, 2013
Two proportional navigation guidance laws based on the rotation of the relative velocity vector are presented. It is shown that the impact angle against a nonstationary target can be controlled through bias addition to guidance commands. The amount of bias to be applied is determined with the help of the expected collision triangle.

Direct impact angle control guidance for passive homing missiles

Proceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace Engineering, 2020
A guidance problem for impact angle control applicable to a missile equipped with a passive seeker is investigated. The proposed guidance law based on the sliding mode control consists of the proportional navigation guidance term with a varying navigation constant and the additional biased term which is a function of the novel sliding surface.

Polynomial guidance law for impact angle control with a seeker look angle limit

Proceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace Engineering, 2019
In this paper, the impact angle control problem is investigated by applying the polynomial shaping method. By shaping the light-of-sight angle with relative range, a guidance law called range polynomial guidance is proposed, and the coefficients are determined by boundary conditions.

Partial Integrated Guidance and Control with Impact Angle Constraints

Journal of Guidance, Control, and Dynamics, 2015
Novel sliding-mode control laws are proposed in this paper to stabilize a class of uncertain nonlinear systems. Considering that the sign function, which is often used in the sliding-mode control can cause chattering of control input, the saturation function is used to take its place in proposed controllers.
