In the implementation of hybrid control strategy, the type and design method of AOEF (Multi-Input Multi-Output System) to improve modal damping and the FXLMS algorithm for closed-loop control channel are proposed. In the helicopter finite element model, two actuators are used to control the vibration of four rows of seats. The simulation shows that hybrid control strategy brings remarkable performance improvement for multi-channel vibration control of helicopter.
