Control strategy and methods of rotor systems by an elastic support / dry friction damper

A proportional integral (PI) controller and continuous gain scheduling proportional integral (GSPI) controller for active control of rotor vibration were developed,according to the characteristics of elastic support/dry friction damper (ESDFD).The theoretical analyses and numerical simulation results show that it is very effective to reduce rotor vibration around the first critical speed by using these control algorithms.Moreover,the continuous GSPI controller has the advantage of giving a well-behaved rotor run-up while maintaining the efficient controlled behavior to attenuate the amplitude of vibration of the first critical speed.
