The Design And Testing Of A Three-Degree-Of-Freedom Small Satellite Simulator Using A Linear Controller With Feedback Linearization And Trajectory Generation, Marina A. Samuels
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
A small satellite simulator with attitude determination and control was designed and implemented in hardware. The simulator consists of inertial sensors for attitude determination and a pyramidal four-wheel momentum exchange system as the control actuators. A linearized PV controller with trajectory generation and feedback linearization was implemented, with the focus on controlling yaw. The simulator was tested on a spherical air bearing platform to allow three-degree-of-freedom operation. The simulator software was developed to read measurements from the sensors, apply the control algorithm, and send commands to the actuators. A data processing routine was developed. Electromechanical testing for the system as …
