Learning objectives
Main aim of this course is to introduce students to basic methods to control the attitude of a spacecraft. Basic tools for analysis and design of control systems will be introduced and applied to spacecraft attitude control. Students will be introduced to a software application that supports analysis and design by those tools.
Requirements
It is required that students know calculus and mechanics, as taught in undergraduate introductory courses.
Competences and learning outcomes
Students will learn mathematical methods useful for analyzing and designing basic attitude control systems for spacecraft. They will also learn to use a software application supporting analysis and design of spacecraft attitude control systems.
Contents (tentative)
Introduction to spacecraft attitude regulation. Spacecraft mathematical model. Attitude regulation neglecting environmental torques. Proportional attitude regulation. Laplace transfrom. Proportional-Derivative (PD) regulation. Asymptotic stability. Attitude regulation with environmental torques. Transfer function. Block diagrams. Feedback control system. Steady-state response to a constant input. Proportional-Integral-Derivative (PID) attitude regulation. Routh's stability criterion. Validations via numerical simulations in Matlab and Simulink.
Evaluation of the student’s training
Students will be evaluated trough an individual exam.
