Course Essentials

Prerequisite: ECE 210.
Text: Franklin, Powell, and Emami-Naeini, Feedback Control of Dynamic Systems, 6th or 7th ed., Prentice Hall. (If you have the 4th or 5th edition, you'll be be able to find most of the same material there, but it will be your responsibility to check the section numbers, exercise numbers, etc. against a later edition.)
Several supplementary texts are available in Grainger reserves.
You must obtain the lab notes from the ECE Store (1031 ECEB) prior to the first meeting of the lab, which will be the week of Jan 23.
Grading policy: Weekly Homework - 15%, Lab - 30%, Midterm Exams (2) - 15% each, Final - 25%. Note: at instructor's discretion, the grade break-up can be changed so that lab contributes 25% and final exam 30%. Homework is due at the beginning of class. No credit will be given for late homework.

Exam info:

If you have a conflict, please let the instructor know immediately. These exams have priority over any other commitments that might come up at a later date.
