This paper describes the active vibration control in the case of steady-state unbalance responses in flexible rotor systems. The control system consists of state feedback to stabilize a system and feedforward control to completely cancel unbalance forces at the designed rotational speed. This is called an output regulation theory with internal stability. At first, unbalance forces are regarded as state variables. Next, a state observer is designed in order to estimate unbalance forces because they cannot be directly measured. Feedforward control forces are produced by an opposite sign of the estimated values based on an observer. This theory has been applied to two kinds of flexible rotor systems, a single degree and two degrees of freedom systems. The amplitudes with control have been experimentally reduced to three percent near the first critical speed and twenty percent near the second critical speed.
