Overview of Recent Automotive Applications of Active Vibration Control

摘要

Modern control applications are becoming increasingly important in the area of vehicle riding comfort. An attractive application in this area is the use of active vibration control in engine mounting concepts, particularly since conventional mounts are approaching their inherent limitations. The standard approach is to isolate the engine and the transmission vibrations from the chassis with rubber or hydro mounts. This mount design is always a compromise between the conflicting requirements of acceptable damping and good isolation. Continental has developed and implemented prototypes of active mounting systems on various test vehicles and demonstrated that significant reductions in noise and vibration levels are achievable. This paper will present an overview of the system components, control algorithms and experimental results.
