This dissertation investigates the non-linear attitude tracking control problem for a remote sensing satellite underactuated by a reaction wheel (RW) actuator fault. First, the fault detection and diagnosis strategy is based on the sliding mode and adaptive sliding mode observers in a finite-time decision window. The failed actuator is excluded from the control [...]

M. Sc. Thesis Author Introduction: First name: Mohammad Last name: Akhtari Entrance year: 2021 Defense date: 2024/August/06 Email address: m.akhtari@email.kntu.ac.ir Title: Implementation of Asteroid Rendezvous Maneuvers in a Hardware in-the-Loop Setup Abstract: This project aims to design, develop, and test a simulation platform for space maneuvers and proximity operations with asteroids. Initially, a three-degree-of freedom air-bearing testbed was constructed, featuring two translational degrees and one rotational degree to simulate the operational environment of a spacecraft. Subsequently, a "dark room" was equipped and set up to mimic space conditions for testing and maneuver operations, ensuring a highly [...]
