Modern control applications will become increasingly important in the area of vehicle riding comfort. An attractive future application in this area is the use of active vibration control in engine mounting concepts, particularly since conventional engine mounts are approaching their inherent limitations. This paper gives an overview of the active control of engine-induced vibrations. After a brief introduction to the requirements that a modern engine mounting concept needs to fulfill, an overview of the history of active noise and vibration control is given. This is followed by a discussion of feedforward and feedback control concepts that have been successfully applied to active noise and vibration control. The paper concludes with a detailed description of an active vibration control system with active absorbers that is used to compensate periodic, engine-induced chassis vibrations.
