ACTIVE VIBRATION CONTROL OF VEHICLE ENGINE-BODY SYSTEM USING H∞ CONTROL METHOD

摘要：

Engine mounts have great effects on the noise and vibration harshness (NVH) characteristics in automobiles.Nowadays the NVH characteristics is becoming a very sensitive issue in the design of passenger cars and thus engineers tend to pay much attention to development of better mounting methods/devices than ever. A prototype active engine mount (AEM) system was developed to improve the NVH characteristics while maintaining high static stiffness to support the engine load. The AEM consists of a conventional hydraulic engine mount and an internal electromagnetic actuator. The robust H∞ controller was adopted to cancel out the force transmitted through the AEM. The experimental result confirmed that can control unwanted vibration from the engine operation by using active mounts system.
