Wave-based control of flexible mechanical systems

here are many contexts, from space structures to disk drive heads, from medical mechanisms to long-arm manipulators, from cranes to robots, in which it is desired to achieve rapid and accurate position control of a system end-point by an actuator working through a flexible system. The system’s actuator must then attempt to reconcile two, potentially conflicting, demands: position control and active vibration damping. Somehow each must be achieved while respecting the other’s requirements.
