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 results useful for analyzing and designing basic attitude stabilization systems for spacecraft.
Contents (tentative)
Introduction to spacecraft attitude stabilization. Active attitude stabilization. Spacecraft mathematical model. Stabilization with respect to impacts. Proportional attitude stabilization. Laplace transfrom. Proportional-Derivative (PD) attitude stabilization. Asymptotic stability. Stabilization with respect to environmental torques. Transfer function. Block diagrams. Feedback control system. Steady-state response to a constant input. Proportional-Integral-Derivative (PID) stabilization. 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.
