Post any questions you have regarding homework assignments here first.
- The final grade will be based on homework sets, a project, two exams and a final exam.
- Homework (0-15%)
- Class text polls (0-10%)
- Pendulum control project (10-20%)
- Exam 1 (0-30%): Monday, February 27, 2012
- Exam 2 (0-30%): Wednesday, April 4, 2012
- Final exam (30-90%): 1:45-3:45pm, Monday, May 7, 2012, 107 Hesburgh Library
- Homework 0 will be each student selecting the grade weightings they desire within the ranges indicated above.
- All examinations except the final are in-class. Any student missing an examination without an excuse from the Office of Student Affairs will receive a grade of zero for that exam.
- Guaranteed grades:
- (overall grade > mean + 1.25 stdev) OR (overall grade > 90%): A-
- (overall grade > mean + 0.25 stdev) OR (overall grade > 80%): B-
- (overall grade > mean - 0.75 stdev) OR (overall grade > 70%): C-
- (overall grade > mean - 2.25 stdev) OR (overall grade > 60%): D
- I am happy to regrade anything that was not properly graded. I tend to collect regrades and save them until I have a critical mass, which is often the very end of the semester. Please write on the front what you want me to regrade and why you think it was not properly graded. If you talk to me in February about it and I regrade it in May there is no way I'll remember what you thought the issue was. Submit it directly to the instructor, not in the stack of regular homeworks. Especially with exams, please consult the grading method that I post for the exam before submitting a regrade request. If it is graded consistently with the posted method, then there is not any point in asking for a regrade.
- Homework sets will be assigned weekly and will be due before the beginning of class on Wednesdays. Late homework will not be accepted without permission from the instructor prior to the time it is due.
- Students must submit their homeworks with their Notre Dame ID number (ndID) written on the homework. Homeworks may be returned on the table outside the elevator on the third floor of Fitzpatrick.
- Collaboration on homework assignments in encouraged. Unless otherwise prohibited, you may consult outside reference materials, other students, the TAs, or the instructor. However, all material that is submitted must be the result of your own individual effort and accurately and substantively reflect your understanding of the subject matter at the time of writing.
- Examples of allowed activities include:
- working on homeworks and projects as a group provided every member of the group submits material that is consistent with paragraph 3 above;
- obtaining help debugging computer programs provided that the computer program submitted is consistent with paragraph 3 above; and,
- consulting another person regarding any aspect of a homework assignment provided that what is ultimately submitted is consistent with paragraph 3 above.
- Examples of dishonest activities include:
- unless expressly allowed by the instructor, submitting material that is not entirely the result of your own intellectual effort;
- submitting material that is intentionally misleading such as plots or graphs that were not generated by an accompanying computer code listing, a computer code listing that is purported to be correct that is not or a homework problem that has the correct answer that does not result from the work preceding it;
- having another person bring your phone to class to text or bringing another person's phone to class to text an answer;
- submitting material that is copied, wholly or in part, in any form; and,
- any activity not expressly allowed above that violates either the letter or spirit of the University Academic Code of Honor.
- You may not consult homework solutions from prior years. If you submit a homework with a mistake that appears on the solution from previous years that is unlikely to happen by chance an investigation into a possible honor code violation will be pursued.
The project will be to program a microcontroller to stabilize an inverted pendulum. There will be two students assigned to each group and each group must have one junior mechanical engineering major in it (because ME juniors take EE 20222). The pendulum will be demonstrated and described on the first day of class. The details of the project will be posted separately, but the entire process will be to determine the mathematical model using a system identification process, relating that to a transfer function, designing a feedback controller using methods from class and implementing the controller on the physical system. There are 10 pendula for use by the class and will be available in Stinson-Remick Hall later in the semester.
Some Student and Professor Obligations:
- I consider it part of my job to make it as easy as possible for you to develop a mature and sophisticated understanding of differential equations, their solution methods and the role they play in engineering. As such, I am happy to answer any and all questions you may have (or to direct you to others, if I think they could do so better) as many times as is necessary to help further this goal, provided that you meet your similar obligation to make a substantive and mature effort to achieve the same goal. Hence:
- If you regularly attend class, are not disruptive, make an effort to make class time productive for yourself and others, outside of class study the material and regularly complete the assignments, I will make every effort to promptly respond to any communication addressed to me.
- If you skip class, are generally disruptive, inattentive, texting, surfing the web, completing other coursework, reading the paper, doing the crossword puzzle, etc., I will answer your questions at a time that is convenient for me, which may be never. If you ask questions regarding administrative matters, e.g., test coverage, that I already announced in class, I will not answer them.
- The required text for the course is Engineering Differential Equations: Theory and Applications by Bill Goodwine.
- Recommended, but not required references are:
- Ogata, Modern Control Engineering,
- Franklin, Powell and Emami-Naeini, Feedback Control of Dynamic Systems,
- Boyce and Diprima, Elementary Differential Equations and Boundary Value Problems.
- This course covers three broad topics: solving systems of linear, first order ordinary differential equations, Laplace transforms and classical control theory.
