Backstepping-Based Impact Time Control Guidance Law for Missiles With Reduced Seeker Field-of-View
IEEE Transactions on Aerospace and Electronic Systems, 2019This paper proposes a guidance law that achieves the desired terminal impact time without violating a seeker's field-of-view (FOV) limits. In order to derive the guidance law, kinematic conditions for impact time control are defined, and the backstepping

A nonlinear guidance law for impact time control
2015 American Control Conference (ACC), 2015This paper discusses the problem of impact time control of an interceptor against a stationary target. A nonlinear guidance law is proposed with the interceptor heading angle variation as a function of the range to target. Closed-form expressions for the design parameters are derived for an exact analysis of the impact time.

Dynamic Route Planning Algorithm with Impact Time Control
Advanced Materials Research, 2014To achieve the tactics mission of cooperative attack at the fixed impact time, for multiple route planning anti-ship missiles, a dynamic route planning algorithm with impact time control is proposed. First, a recursive route planning algorithm is designed to choose navigation points and come to a reference route.

Time course of cellular pathology after controlled cortical impact injury
Experimental Neurology, 2003Several different models of brain trauma are currently used and each simulates different aspects of the clinical condition and to varying degrees of accuracy. While numerous studies have characterized the cellular pathology after weight-drop or fluid percussion injury, detailed information on the histopathology that evolves after the controlled ...

Impact time and angle control guidance independent of time-to-go prediction
Aerospace Science and Technology, 2019Abstract A novel cruise guidance method that can meet the terminal latitude and longitude, time and angle constraints independent of time-to-go prediction is studied in this paper. The impact time and angle control guidance (ITACG) goal is achieved through two steps.

Impact Time Control Guidance Law for Guided Projectile Considering Time-Varying Velocity
2019 SICE International Symposium on Control Systems (SICE ISCS), 2019A novel impact time control guidance law for guided projectile considering time-varying velocity is presented based on linearized relative motion model, optimal control theory and trajectory prediction algorithm. In the process of deriving the guidance law, a time-to-go estimation formula for guided projectile with time-varying velocity is also ...
