英文摘要

      A quardratic objective function in frequency domain is presented in this paper under consideration of the speciality that a gyroscopic matrix exists in the system matrix. Three main function of active vibration control of the rotors are indicated based on characters of vibration faults of the rotors. Respective design methods of controllers are described. A model cantilever rotor is analyzed to show how to realize these control methods and how about the control effect. Results of analysis show that effect of the control methods suggested in this paper is pretty well, all of the methods have improtant perspective for application.
