Research of Rotor Hub Mounted Vibration Suppression System

In order to replace the bifilar at the top of the rotor hub with a lighter active vibration control system, an actuator suitable for hub vibration active control was designed. The method of offset eccentric mass was adopted in the design, which can effectively deal with fault states. And the actuator control algorithm was developed as well. The output force control performance of the actuator was verified through test. Relying on the above work, a set of active vibration control system scheme for suppress hub mounted vibration was proposed. The software and hardware of the active vibration control system were built based on DSP controller and servo driver. Finally, the upper and host computers of the active vibration control system were developed based on LABVIEW and CCS separately, laying the foundation for the subsequent experimental research.
