Abstract

An active control engine mount (ACM) system has been developed which consists of an electromagnetic actuator and a hydraulic mount. This system incorporates an adaptive control strategy based on the synchronized filtered-X LMS (SFX) algorithm. The crank angle pulse signal is detected as the synchronization signal and the force transmitted to the car body through the engine mounts is detected as a residual signal. Application of the ACM system to a vehicle with a transversally mounted four-cylinder engine has resulted in a significant reduction of idling vibration and booming noise.
