### Vår 2024

# STE-3605 Mathematical Modeling and Simulation - 5 stp

## The course is administrated by

Institutt for elektroteknologi

## Type of course

The course cannot be taken as a single course. The course is reserved for students belonging to Aerospace Control Engineering

## Course contents

This course teaches the students how to build a satellite simulator through a series of tutorial-like lectures with accompanying assignments. Through a series of 10 assignments, the students will be able to model and simulate a satellite operating in an elliptical orbit. Specifically, the course will cover:

- Orbital Mechanics
- Sun vector modelling
- Magnetic field modelling
- Attitude determination
- Attitude control
- Actuators
- Thrusters
- Reaction wheels
- Magnetic torquers

- Actuation strategies
- Bang-bang
- Pulse width modulation
- Pulse width pulse frequency modulation

- Sensors and sensor noise

## Objective of the course

After passing the course, students will have the following learning outcomes:

**Knowledge and understanding:**

The candidate:

- has knowledge on how to model translational and rotational dynamics of spacecraft
- has knowledge on how to design an attitude controller for a rigid body
- has knowledge on how to estimate the attitude based on vector measurements

**Skills:**

The candidate:

- is able to model different components required to build a satellite simulator
- is able to perform simulations in Matlab/Simulink
- is able to communicate and discuss advanced concepts

**Competence:**

- The candidate will be able to model and simulate complex systems in Matlab/Simulink.

## Language of instruction

The instruction language is English in case of international students participating, if not it will be taught in Norwegian.

## Teaching methods

The students will receive teaching in advanced mathematical modeling and will spend much of the time doing one assignment each day, 10 in total. Through these assignments the students will learn the course contents through practical use of Matlab/Simulink closely supervised by the instructor.
