Abstract

This presentation will discuss the numerical methods for trajectory optimization. In the past a few decades, different methods for trajectory optimization had been proposed. By the investigation of a bibliography of papers and cases for using some of these methods, various trajectory optimization methods will be categorized and their possible applications will be discussed. This presentation will focus on the optimization methods which are distinguished by the transformation method of the continuous optimal control problem, parameterization methods for control and so on. It is hoped that this presentation can be a guide for those who begin to do research in the field of trajectory optimization as well as issues which can be described as an optimal control problem. There will be a summary of research on the Near-Earth Objects rendezvous trajectory optimization base on the Gauss Pseudospectral method.

Biography

Dr Enmi Yong received her PhD, on trajectory optimization and guidance for hypersonic glide re-entry vehicle, from the National University of Defence Technology of China in 2008. She joined the flight dynamic research group in Chinese Aerodynamic Research and Development Centre (CARDC) in 2009, where she led a project of trajectory design and flight simulation for a lifting-type re-entry vehicle, and also participated in the program of Integration of flight dynamics/aerodynamics/ aerothermodynamics simulation for a hypersonic vehicle, and the re-entry guidance for a return capsule in moon exploration mission. She is currently a visiting scholar at School Engineering, University of Glasgow, and works on the Near-Earth Objects rendezvous trajectory planning problem.
