BACKGROUND INFORMATION:
This course is a
continuation of the course entitled, Introduction to Smart Materials and
Structures (Intelligent Structural Systems), which has been offered in the
Department of Mechanical Engineering. This course will be initially taught as a
special topic course, and eventually as a regular graduate level course (700)
in the Department of Mechanical Engineering. Knowledge about smart materials
and controls are prerequisite to take this course.
COURSE OBJECTIVES:
The objective of this course is to enable students to have necessary and advanced knowledge in control of smart materials and structures. This is a special topic course and it is research oriented. There will be no exams but innovation and research oriented projects will be heavily involved.

1. Review of smart materials and
structures.
Topic 2. Aerospace applications of control of
smart structures
Topic 3 Review of classical controls.

Please notes:
- The order of actual teaching may be different from the above
sequence.
- The content of actual teaching may be different from the above
outline.
- Several speakers with expertise in smart materials and structures will deliver lectures.
- Experimental demonstrations will be used to assist teaching.
The Smart
Materials and Structures Teaching Laboratory will host this course and the
experiments in this laboratory will be used as demonstrations.
In this course, you are required to finish two main projects (the
midterm project and the final project) and several small projects. For each
project, you are required to hand in a report.
Experimental and hands-on
project maybe involved.
Homeworks will be very limited if there is any.
