Learning Outcomes

The module provides the theory and practical application of spacecraft dynamics and control. The students learn all relevant elements for analyzing, designing, modelling and implementing an attitude control system. After successful completion of this module, students will be able to: - explain and interpret the basic terms and concepts of classical control theory, - analyse the properties of linear systems, - design controllers for linear systems, - use standard software for the analysis of controlled systems and the design of controllers, - explain and interpret the basics and methods related to state space control, - derive the requirements for an attitude control subsystem from the mission objectives, - explain the basic terms and concepts related to spacecraft attitude control, - identify and calculate different methods for attitude parameterization and compare their advantages and limiting cases, - identify and calculate/use different methods for attitude determination and their limitations, - analyze the kinematics of attitude control and develop the kinematics model for a spacecraft, - analyze the dynamics of a rigid body and develop the dynamics model for a spacecraft, - model and demonstrate different spacecraft sensors and actuators, - develop kinematics and dynamic models for a real system in three-axis, - design and demonstrate single-axis attitude control maneuvers on a real system using the methods of classical control theory.

Description of Teaching and Learning Methods

The module is divided into two parts, Spacecraft Dynamics and Control 1 and Spacecraft Dynamics and Control 2. The module starts with Spacecraft Dynamics and Control 1, where the basic concepts and methods of classical control theory, model-based state prediction, and state-space control are taught with relevant examples. Spacecraft Dynamics and Control 1 consists of theoretical lectures and homework. The module continues with the second part, Spacecraft Dynamics and Control 2, where the students learn about the requirements for an attitude control subsystem, parameterization of spacecraft attitude, kinematics and dynamics of spacecraft attitude, and spacecraft attitude determination techniques. The students will then apply their theoretical knowledge of attitude dynamics and control theory in a hands-on project. In the project, single-axis attitude control maneuvers are implemented on a FloatSat (a satellite-like system with sensors and actuators that floats on an air-bearing table). Spacecraft Dynamics and Control 2 consists of theoretical lectures, homework, programming assignments, and group project work.
