ANNOUNCEMENTS |
This course will be offered in Spring 2018.
SUMMARY |
Course Description
The analysis and design of continuous and time-discrete linear feedback control
systems with a focus on frequency domain models. Simulation using Scilab/xcos to
design controllers for steady-state
error reduction and optimal transient response to varied inputs.
Prerequisites: ENGR/ELEE 4210 (Linear Systems) or Permission of Department.
CONTENTS |
INTRODUCTION |
Consistent with this philosophy, there will be quizzes and a semester project. The quizzes can be regarded as short homeworks with a theoretical emphasis. These will allow you to strengthen your understanding of the theory and to assess your preparation for the exams. The semester project allows you to build an actual feedback control system. All aspects are covered, from design of the process (or plant) and the sensors to the theory of the necessary control system to the controller implementation. No specific path to the solution is prescribed, and you have wide design flexibility.

Grading Milestone | Due Date |
1: Team nomination |
Grading Milestone #1 requires paper turnin! Create a formal cover page for your project report. The cover page should contain the names of all team members and the project you decide to pursue. Turn in a paper copy in class.
Team presentations are a short video approximately between 5 and 7 minutes long. The video should capture the following topics:
