This paper continues the previous effort on the development of a trajectory generation
platform that assures minimum-control expenditure and collision-free manoeuvre of a …

Direct optimization of many-revolution spacecraft trajectories requires path discretization into
segments. The well-known Sundman transformation guides the development of a piecewise …

This paper presents a trajectory-optimization method for a chaser spacecraft operating in
ultra-close proximity to a failed satellite. Based on the combination of active and passive …

An effective pseudospectral method is proposed for dynamic optimization problems, the aim
of which is to maximize production of these problems in chemical engineering. Several …

In [1], we inaugurated a new area of optimal control (OC) theory that we called" periodic
fractional OC theory," which was developed to find optimal ways to periodically control a …

This paper investigates cooperative trajectory planning of multiple unmanned combat aerial
vehicles (multi‐UCAV) in performing autonomous cooperative air‐to‐ground target attack …

A piecewise-constant Sundman transformation is introduced for a spacecraft trajectory
discretized into many segments. The piecewise-constant Sundman transformation is a …

Improvement of spacecraft trajectory optimization approaches, methods, and techniques is
critical for better mission design. Preliminary low-fidelity analysis precedes high-fidelity …

Trajectory design plays an important role in the overall design optimization of an aero-craft.
As a classic method to solve trajectory optimization design problem, the indirect method is …

Regular perturbation method (ie direct expansion method) is a technique used for solving
the asymptotic power series of solutions to regular perturbation problems. By assuming that …
