Adaptive system for landingapproach trajectory of JAS 39Gripen / Adaptivt system för inflygningstrajektoria för JAS 39 Gripen

Strömblad, Emil, Karlsson, Pontus January 2023 (has links)
The landing procedure of an aircraft is a safety critical procedure requiring high precisioncontrol and feasible trajectories to follow from the current state. This thesis implementsand studies a complete system with trajectory planning, trajectory following, and steeringcommand generation. Dubin’s path is the method implemented for the feasibility ofthe planned trajectory, with the extended implementation of variable speed and verticalmovement. It is important to reach but not exceed the aircraft limitations and considerthe control signals’ physical boundaries. A Model Predictive Controller is implementedto abide by constraints and preferences on the states and control signal. The systemsuccessfully generates and follows the planned trajectory with the models established inthis thesis. The resulting steering command from the created system would be moreintuitive for the pilot than the currently used approach, but it can not conclude whetherthe simulated results are a true indication of functionality, further tests in a more extensivesimulation environment are needed for a definitive answer.
