Computational Methods for Control of Vibration

( This session will run until 8:00 PM )

"Control of Vibration" is an emerging interdisciplinary area blending control theory in electrical engineering and vibration theory in mechanical engineering. Solutions of several practical problems; such as the design of large space structures, or control of power systems, require expertise from both areas of engineering and mathematical sciences. Unfortunately, many existing methods for solving control problems in vibration engineering do not make use of the modern sophisticated techniques of scientific matrix computations. Furthermore, some of the techniques used in common engineering practice, such as, modal space control techniques, are unpractical for large and sparse problems that can occur in applications.

This minisymposium will focus on related, important problems in this area: Feedback Stabilization, Eigenvalue Assignment and Inverse problems. The speakers will discuss the state-of-the-art techniques for these problems.
