# Syllabus for ME 370 System Dynamics and Control

Spring 2017

## Course description

This course is an introduction to the mathematical modeling and control of systems of electrical, mechanical, fluid, thermal, and inter-domain (e.g. electro-mechanical) elements. A system dynamical approach is used, which allows different energy domains to be modeled within a unified framework. Analysis includes the time-domain and frequency-domain. Control systems topics include stability, steady-state errors, and root-locus design. (Adapted from the course catalog.)

3. Take the weekly homework quiz.

### Assignment #6

2. RW Problems 14.1, 14.3, 14.4, 14.6, and 14.8 (sketch by hand and check in MATLAB).
3. Suggested RW Problems 14.12 and 14.21.
4. Suggested problem to help you connect pole-zero plots to Bode plots: RW Problem 14.9.

3. Take the weekly homework quiz.

### Assignment #8

2. RW Problems 15.12, 15.13, 15.17, and 15.18 (this last one will probably require some reading of the chapter).
3. Take the weekly homework quiz.

### Assignment #9

2. Nise Problems 6.1, 6.5, 6.11, 6.17, 6.19, 6.23, and 6.31.

## Resources

Class resources will be posted here throughout the semester.

## Project

There’s going to be a design project. It’s going to be the best project. Everybody’s saying it. It’s going to be huge.

## Video lectures

Most lectures will be available online on my YouTube channel. I recommend subscribing and familiarizing yourself with the playlist for this course.

## Slack

Everyone is required to join the messaging service called “Slack.” We’ll use it to communicate with each other during the semester. The Slack team you need to join is called me370-2017s. That was a signup link, right there.

## Homework, quiz, & exam policies

### Homework & homework quiz policies

Weekly homework will be “due” on Wednesdays, but it will not be turned in for credit. However — and this is very important — each week a quiz will be given that will cover that week’s homework.

Quizzes will be available on moodle each week (as early as I can get them up), and must be completed by Sunday (before midnight). Late quizzes will receive no credit. Multiple attempts may be made on the quizzes (you will receive your mean grade).

Working in groups on homework is strongly encouraged, but quizzes must be completed individually.

### Exam policies

The midterm and final exams will be in-class. If you require any specific accommodations, please contact me.

Calculators will be allowed. Only ones own notes and the notes provided by the instructor will be allowed. No communication-devices will be allowed.

No exam may be taken early. Makeup exams require a doctor’s note excusing the absence during the exam.

The final exam will be cumulative.

Total grades in the course may be curved, but individual homework quizzes and exams will not be. They will be available on moodle throughout the semester.

Cheating or plagiarism of any kind is not tolerated and will result in a failing grade (“F”) in the course. I take this very seriously. Engineering is an academic and professional discipline that requires integrity. I expect students to consider their integrity of conduct to be their highest consideration with regard to the course material.

## Correlation of course & program outcomes
