Dynamics and Control of Structures

This book addresses problems in structural dynamics and control encountered in such applications as: robotics, aerospace structures, earthquake-damage prevention, and active noise suppression. The treatment combines concepts from control engineering (such as system norms and controllability) and structural engineering (such as modal properties and modal models), thereby both revealing new structural properties as well as giving new insights into well-known laws. Matlab codes for many of the procedures and methods discussed in the book are included.
