Sliding Mode Guidance Law for Impact Time Control Without Explicit Time-to-Go Estimation
IEEE Transactions on Aerospace and Electronic Systems, 2019This paper presents an impact time control guidance law that does not perform explicit time-to-go estimation. In order to satisfy the interception and the desired impact time constraint simultaneously, a sliding surface variable formulated as a sum of ...

A computational-geometry-based 3-dimensional guidance law to control impact time and angle
, 2020In this paper, a new guidance law is proposed based on computational geometry with impact time and angle constraints against a stationary target in three dimensions. The law is based on the principle of following a specified trajectory toward the target,

Time & Society, 1996
The increasingly technical nature of the industrial way of life has brought about dramatic changes in the temporality of socio-environmental problems. Local, short-term, acute disturbances in the environment have turned into global, long-term, chronic perturbations, and yet both the scientific and socio-political solutions offered for environmental ...

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

Modeling market impact and timing risk in volume time
Algorithmic Finance, 2013Intraday volatility and market impact models in volume time are proposed. We build an intraday volatility profile to capture non-stationarity of intraday price returns and utilize a fractional Brownian motion process to measure deviations from square root scaling rule of volatility.

Terminal sliding mode control based impact time and angle constrained guidance
Aerospace Science and Technology, 2019In this paper, an impact time and angle constrained guidance (ITACG) is proposed based on the nonsingular terminal sliding mode control (NTSMC) theory. First, the guidance law is derived for stationary targets.
