Abstract: An active control strategy with online secondary path modeling is proposed and applied in active control of helicopter structural vibration. It is compared with existing method based on a helicopter model and MIMO active control simulation is conducted. The results show that the proposed method is able to produce superior performance compared with the existing method and reduce the structural vibration of helicopter effectively.

Key words: helicopter structural vibration, online secondary path modeling, multi-input, multi-output, active control
