ME 451-Control Systems, Fall 2008

Announcements

- The final review session is scheduled 1-2 pm on Tuesday, December 9th at 2400 Engineering Building. Good luck!
- You are allowed to bring a letter sized paper (two sides) with hand-written formulas.
- The scope is cumurative and up to Lecture 23.

- The second midterm exam will be in the class on 11/10/08 Monday. The scope is up to hw7.
- In the exam, you are allowed to bring a letter sized paper (one side) where you can write important formulas and equations. It has to be only with your hand-written formulas.
- Check ME451 Control Systems Spring 2007 and ME451 Control Systems Fall 2005.
- Review session on Nov. 7 Friday.
- The first midterm exam will be in the class 10/3/08 Friday. The scope contains materials covered in Lecture 0- Lecture 6, i.e., from hw1 to hw3. If you can solve homework problems well, you will do great in the exam.
- In the exam, I will allow you to bring a letter sized paper (one side for mid terms and two sides for the final exam) where you can write important formulas and equations. It has to be only with your hand-written formulas.
- You can find some test examples along with solutions in ME451 Control Systems Spring 2007 and ME451 Control Systems Fall 2005.
- TA Yunfei will go over several problems for the the midterm exam on Monday 9/29/08 and Wednesday 10/1/08.

- For those of you who don't want to take notes in class, the complete notes without empty spaces will be also posted. However, taking notes in class is highly recommended.
- There will be often blank spaces for the solutions to the example problems in the posted slides so that students are encouraged to fill them up with correct solutions from the class.
- Some references are posted.
- 8/28 HW1 and the quiz solution are posted.
- Homework grading policy
- If all problems are solved (not necessarily correct), 50% of the credit will be given. If only some of problems are solved, this 50% of the credit will be prorated.
- Each homework, randomly chosen a subset of problems will be graded carefully, which will make up for the other 50% of the credit.
- The solution of the homework will be posted on the class webpage.
- Late homework will not be accepted unless you prove (with some documents) that your case is legitimate to TA.
