Abstract
In order to meet the needs of active control of rotor vibration of high performance aero-engine， an active control model was established based on the active elastic support/dry friction damper，and a switch controller and a PI (proportional-integral) controller were designed according to the modal control strategy. Then， simulation analysis and experimental verification were carried out with a certain type of aero-engine high pressure rotor tester as the object. The results showed that the switch control and PI control methods designed according to the modal control strategy effectively reduced the vibration of the rotor passing through critical speed by up to 96.17%. In addition，compared with switch control method，PI control method was more conducive to rotor stability，and it can achieve control objectives at lower cost，thanks to its control ability to react in real time to vibration under various working conditions.
