Two variable velocity feedback control methods were proposed in the first report. One is the design in a actual domain and the other is the design in a modal domain. These two methods not only realize an optimal pole assignment for the controlled modes, but also have no effect on the uncontrolled modes. The latter method has a wide range of applications and a general character. We have applied these methods to a flexible rotor system. The test rotor is supported by linear actuators through bearing housings which we call active control bearings. There are three critical speeds, up to 3000 rpm. The variable velocity feedback control system design is based on an experimental modal analysis instead of a mathematical model. We have completely controlled three modes by means of a digital controller. The unbalance responses with variable velocity feedback are similar to the unbalance responses with an ideal model control.
