Motion planning and control system design are crucial in the development of unmanned aerial vehicles (UAVs) for various applications. To maximize the mission performance, trajectory design is often performed to minimize ...

Autonomous vehicles are becoming increasingly popular, requiring efficient and reliable methods for trajectory generation and path planning. A common approach is to convert the original continuous-time optimization problem ...

The high costs of space missions necessitate optimization across all mission aspects, particularly fuel consumption, which impacts both economic feasibility and payload capacity. Electric propulsion systems, with higher ...

Rendezvous maneuvers are designed to match the position and velocity vectors of a target body (e.g., planet, comet, satellite) whereas transfer maneuvers are designed to match the orbital elements of the target body, except ...

Spacecraft trajectory optimization is an essential task in space mission design. The propulsion system of the spacecraft can affect the type of trajectories that can be realized by a spacecraft. In the past few decades, ...

This dissertation reviews and presents a computational framework for robust spacecraft trajectory optimization under uncertainty, advancing beyond deterministic methods to ensure mission reliability in low-thrust interplanetary ...
