International Journal of Robust and Nonlinear Control, 2023
This article proposes a three‐dimensional impact time control guidance (ITCG) law without using time‐to‐go estimation, where the constrained field‐of‐view (FOV) is also considered. The guidance law design process is divided into two steps.

Quartic range shaping for impact time control
2017 25th Mediterranean Conference on Control and Automation (MED), 2017A guidance problem with the impact time constraint is considered under nonlinear kinematics. The guidance design makes the range to the stationary target behave as a quartic polynomial in time. The analytical availability of the polynomial coefficients provides a feasible basis.

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 ...

Finite-Time Cooperative Guidance Strategy for Impact Angle and Time Control
IEEE Transactions on Aerospace and Electronic Systems, 2021In this article, two cooperative guidance schemes with impact angle and time constraints are proposed for multiple missiles cooperatively intercepting a maneuvering target in the presence or absence of a leader missile. First, cooperative interception with impact angle constraint is formulated based on the relative motion equation between the ...

Nonsingular Sliding Mode Guidance for Impact Time Control
Journal of Guidance, Control, and Dynamics, 2016A guidance problem for impact time control applicable to salvo attacks is considered based on the sliding mode control. To prevent the singularity of the guidance command, a positive continuous nonlinear function of the lead angle is introduced to the guidance command, which makes the Lyapunov stability negative-semidefinite.

Sliding mode–based simultaneous control of impact angle and impact time
Proceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace Engineering, 2021In 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 its rate, while the requirement of impact time is achieved by tracking the desired time-to-go.

Impact time constrained integrated guidance and control design
Aerospace Science and Technology, 2021Abstract This paper proposes integrated guidance and control design to intercept a target, which may execute various motions, at a pre-specified time of interception. The problem is addressed considering nonlinear engagement kinematics and the interceptor is steered using the combined effects of canard as well as tail configurations (dual-controlled ...

Minimum-Effort Impact-Time Control Guidance Using Quadratic Kinematics Approximation
Journal of Guidance Control and Dynamics, 2021A guidance law for intercepting a stationary target is derived based on solving the minimum effort optimal control problem with fixed terminal time and a quadratic approximation of the kinematic eq...

Impact Time and Angle Control Guidance
AIAA Guidance, Navigation, and Control Conference, 2015In 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.

Guidance Law to Control Impact Time and Angle
2005 International Conference on Control and Automation, 2005This paper proposes a new guidance law to control both impact time and impact angle for a flight vehicle's homing problem, which can be applied for an efficient salvo attack of antiship missiles or a cooperative mission of unmanned aerial vehicles (UAVs).
