Can we control the position and vibration, simultaneously, of a flexible link with a tip mass using only the actuator's input?

This is a boundary control problem of a hybrid ODE-PDE system. The system consists of an actuator, a flexible link fixed to the actuator, and a tip mass at the free end of the link. In most...
