Vibration is a natural phenomenon that occurs in a variety of engineering systems.
In many circumstances, vibration greatly affects the nature of engineering design
as it often dictates limiting factors in the performance of the system. The
conventional treatment is to redesign the system or to use passive damping. The
former could be a costly exercise, while the latter is only effective at higher
frequencies. Active control techniques have emerged as viable technologies to
fill this low-frequency gap. This book is concerned with the study of feedback
controllers for vibration control of flexible structures, with a view to minimizing
vibration over the entire body of the structure.
