Syllabus for ME 370 System Dynamics and Control

a syllabus

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. Feedback control systems are introduced. (Adapted from the course catalog.)

Textbooks

(RW) Derek Rowell and David N. Wormley. System Dynamics: An Introduction. Prentice Hall, 1997. (Required.)

Homebrew texts and notes

Partial texts (with fill-ins) I’m writing will be posted on the Dynamic Systems (henceforth: Dy) and Control: an introduction (henceforth: Co) pages.

These texts are being constantly revised, so you have two printing options I recommend (both in color!):

  1. Have a service such as that of the SMU Computer Resource Center print them in bulk for you. Whichever printing service you use, I recommend binding them such that pages can be replaced (e.g. three-ring bindable) in case there are major revisions to a section during the term.
  2. Print each week’s lectures on-demand, yourself, when I give the “ok to print” signal. This is more tedious and requires more organization, but it’s at least a bit less paper.

In either case, you are required to have a binder (or equivalent) with Dynamic Systems Chapter lti ready to show by our second class to avoid a 10% deduction on your first quiz grade. (Or you can show me those lectures on your note-taking tablet, if that’s your preferred method.)

Throughout the semester, you should be ready to show these (current) in any class, with threat of a 10% quiz grade deduction for that week.

Video pre-class lectures

Before every class, there will be one or more video lectures you will be required to watch! See the Schedule. I’ve uploaded them all to YouTube. Watch them with the texts printed out, filling in the blank sections as you go.

I recommend subscribing and familiarizing yourself with the playlists for this course.

The first is the Dynamic Systems playlist.

The second is the Control Systems I playlist, of which we will only watch a few lectures, toward the end of the course.

Homework, quiz, & exam policies

Homework & homework quiz policies

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

Quizzes will be available on moodle each Friday, and must be completed by that evening (before midnight). Late quizzes will receive no credit.

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

Exam policies

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

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

Grading policies

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.

Academic integrity policy

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.

Cheating is academic dishonesty as well as unprofessional for prospective teachers. Do not copy other students' assignments, have someone else write your papers or plagiarize published or unpublished materials, or submit work previously graded by other instructors. See Saint Martin's University Student Handbook. Students will be graded not only on their academic success, but on professional conduct as well. Students who fail to show professionalism in their academic or personal conduct (e.g. constant tardiness, excessive absences, and/or other unprofessional behavior) may earn a lower letter grade than the total of semester accumulated points, or may even earn a failing grade.

What is academic integrity? Saint Martin’s University is a community of faculty, students and staff engaged in the exchange of ideas in the ongoing pursuit of academic excellence. Essential to our mission is a focused commitment to scholarly values and intellectual integrity, and a respect for the ideas, beliefs and work of others. This commitment extends to all aspects of academic performance. All members are expected to abide by ethical standards both in their conduct and their exercise of responsibility to themselves and toward other members of the community. As an expression of our shared belief in the Benedictine tradition, we support the intellectual, social, emotional, physical and spiritual nurturing of students.

What is academic dishonesty? Saint Martin’s University defines academic dishonesty as violating the academic integrity of an assignment, test and/or evaluation of any coursework. This dishonest practice occurs when you seek to gain for yourself or another an academic advantage by deception or other dishonest means. You have a responsibility to understand the requirements that apply to particular assessments and to be aware of acceptable academic practice regarding the use of material prepared by others. Therefore, it is your responsibility to be familiar with the policies surrounding academic dishonesty as these may differ from other institutions.

Access and accommodations

Your experience in this class is important to me. If you have already established accommodations with Disability Support Services (DSS), please communicate your approved accommodations to me at your earliest convenience so we can discuss your needs in this course.

If you have not yet established services through DSS, but have a temporary health condition or permanent disability that requires accommodations (conditions include but are not limited to mental health, attention-related, learning, vision, hearing, physical or health impacts), you are welcome to contact DSS at 360-438-4580 or dss.testing@stmartin.edu or smu.dss@stmartin.edu. DSS offers resources and coordinates reasonable accommodations for students with disabilities and/or temporary health conditions. Reasonable accommodations are established through an interactive process between you, your instructor(s) and DSS. It is the policy and practice of the Saint Martin’s University to create inclusive and accessible learning environments consistent with federal and state law.

Sexual misconduct/sexual harassment reporting

Saint Martin’s University is committed to providing an environment free from sex discrimination, including sexual harassment and sexual violence. There are Title IX/sexual harassment posters around campus that include the contact information for confidential reporting and formal reporting. Confidential reporting is where you can talk about incidents of sexual harassment and gender-based crimes including sexual assault, stalking, and domestic/relationship violence. This confidential resource can help you without having to report your situation to the formal reporting process through the Dean of Students – Ms. Melanie Richardson, Associate VP of Human Resources – Ms. Cynthia Johnson, Public Safety – Ms. Sharon Schnebly, or the Office of the Provost – Dr. Kathleen Boyle, unless you request that they make a report. Please be aware that, in compliance with Title IX and under the Saint Martin’s University policies, educators must report incidents of sexual harassment and gender-based crimes including sexual assault, stalking, and domestic/relationship violence. If you disclose any of these situations in class, on papers, or to me personally, I am required to report it.

University sanctioned activities

If a student is absent from class due to university sanctioned activities, such as sports, it is the student's responsibility to request that the absence be excused, otherwise, the absence will be recorded as unexcused. Absent students are responsible for catching up with the class, and if any assignments are due on the day of the absence, it is the student's responsibility to turn in the assignments on time (prior to class).

Religious Accommodation

Saint Martin’s University, in honor of the sacredness of the individual, and being deeply rooted in the Catholic Benedictine tradition of higher education, values the many religious and spiritual practices of our campus community. Saint Martin’s University supports our students in their ongoing journey of becoming. In compliance with Washington State Law RCW 28B.137.010, Saint Martin’s University reasonably accommodates students for reasons of religious observances.

Center for Learning, Writing, and Advising

The Center for Student Success offers free academic services for all Saint Martin’s students. The Center provides subject-area peer tutoring in science, technology, nursing, engineering, math, business, accounting, economics, world languages and other subjects. At the Writing Center, students meet with writing tutors to discuss their academic, personal, and professional writing. The Advising Center works with students on academic advising, connecting with campus support resources, transition and self-exploration guidance, personalized academic improvement plans, learning workshops, and support for changing majors. Disability Support Services is also located in the Center for any student with a disability who needs accommodations. For more information on the Center for Student Success, or to sign up for a tutoring, advising, or DSS meeting, see the website: stmartin.libcal.com/appointments.
