摘要
Active Vibration Control System( 110 )Including multiple actuators( 150-155 )It is corresponding,And close to each engine( 102 )Aircraft( 100 ),At least one sensor( 650 )In the main cabin for being located at aircraft( 100C ) ( 100 ),And be configured to the vibration of detection amplitude and frequency and sound generate it is one or more by respective engine( 102 ),And generate one or more vibrations and acoustic feedback signal,Controller( 500 )It is connected to multiple actuators( 110 )0 and at least one each described sensor( 110 )1,Controller( 110 )2 are configured to realize multiple actuators that control is no more than two( 110 )3 ( 110 )4 each engines are based on the feedback signal and are being no more than two actuators( 110 )5 effects inhibit one or more vibrations and the respective engine of sound due to the respective engine of rotary shaft( 110 )6.
