Description including Unit Aims

In this unit, we will analyse the behaviour of smart structures such as beams and plates, which can be controlled using sensors and actuators. The course covers analytical methods to determine vibration behaviour and then apply active vibration control and shape change to structures. Nonlinear methods are emphasised throughout in order to account for geometric and material nonlinear behaviour which typically occurs in smart structures.

Aims:

The aim of this course is to examine and explain the nonlinear vibration and control of smart structural elements such as beams and plates. Nonlinear vibration and control methods will be examined.

Intended Learning Outcomes

By the end of this course, students will know how to do the following:

1. Calculate the nonlinear dynamic behaviour of beams, cables and plates.
2. Derive models for beams with a piezo actuator attached.
3. Use positive position feedback to reduced unwanted vibration in structural elements.
4. Analyse Hopf bifurcation behaviour in flexible structures.
5. Apply feedback linearization control to flexible structures.

Teaching Information

Students receive a 1-hour lecture each week over 21 weeks. Examples of similar standard to examination questions are provided. Students are expected to work through these examples and previous years' examination papers in their own time. This will help to inform them of their real understanding of the subject.

Assessment Information

There is a 2-hour written paper in the summer which counts for 100%.
