Learning outcomes |
To give to the students the necessary skills related to modeling, analysis and design methods that focus on 4D navigation trajectory optimization and control. In that scope, the lectures will deal with methods and examples that are applicable to commercial aircraft, UAVs, missiles and spacecraft.

Syllabus |
Module I (Models and Processing of Aerospace Trajectories) - Problems related to 4D trajectory optimization and control. Air trajectory models. Space trajectory models. Kalman filtering. 4D trajectory estimation and reconstruction.
Module II (Flight Trajectory Optimization) - Static (parametric) optimization methods and algorithms. Dynamic optimization methods and algorithms (direct methods and indirect methods). 4D trajectory optimization (atmospheric flight and space flight).
Module III (Trajectory Control) - Optimal trajectory control using the LQR and H-infinity methods. Trajectory controller design (for commercial aircraft, UAVs, missiles and spacecraft).
