Cooperative Guidance of Seeker-Less Missiles for Precise Hit

Abstract

A novel cooperative guidance scenario is proposed that implements fire-and-forget attacks for seeker-less missiles with a cheap finder for stationary targets and without requiring real-time communication among missiles or precise position information. Within the proposed cooperative scenario, the classic leader-follower framework is utilized, and a two-stage cooperative guidance law is derived for the seeker-less missile. Linear-quadratic optimal control and biased proportional navigation guidance (PNG) are employed to develop this two-stage cooperative guidance law to minimize the control cost in the first stage and to reduce the maximum acceleration command in the second stage when the acceleration command is continuous. Simulations and comparisons are conducted that demonstrate the effectiveness and advantages of the proposed guidance law.

Distributed observer‐based fixed‐time cooperative guidance law against maneuvering target

“…Remark 5. Unlike the cooperative guidance method for seeker-less followers proposed by Zhao and Xiong, 40 the strategy proposed in this paper escapes from the strict assumption that the leader flies straight. In addition, it can also satisfy the need to attack maneuvering targets.…”

Optimal control of combination immunotherapy for a virtual murine cohort in a glioblastoma-immune dynamics model

“…The goal of optimal control is to find the “controls” for a dynamical system which allow us to reach a desired outcome by minimizing (or maximizing) an objective functional. Optimal control theory has been used to optimize policies and practices for a wide variety of industries including economics (Sheng et al (2014); Wu et al (2015); Li et al (2019); Kaszkurewicz and Bhaya (2022)), aerospace technologies (Benson (2005); Longuski et al (2014); Villegas Díaz et al (2019); García-Heras et al (2019); Sun et al (2019); Zhao et al (2019)), and the medical field (Martin and Teo (1994); Jung et al (2002); Ledzewicz et al (2013); Wang and Schättler (2016); Ledzewicz and Moore (2017); Ratajczyk et al (2018); Moore et al (2018); Fernández and Pola (2019); Ledzewicz et al (2019); Gutiérrez-Diez and Russo (2020); Jarrett et al (2020); Sharp et al (2020); Rautela et al (2023); Luo et al (2023); Valega-Mackenzie et al (2024)). Control theory was even used in the development of the “artificial pancreas,” which became FDA approved in 2016 for patients with type 1 diabetes (FDA (2016)).…”
