MODELING AND IDENTIFICATION OF A PNEUMATIC AIR SPRING-VALVE-ACCUMULATOR SYSTEM FOR SEMI-ACTIVE SUSPENSION CONTROL

摘要

This paper presents the analytical modeling, system identification, and experimental validation for an air spring-valve-accumulator pneumatic system. Such system has wide spread use in vibration isolation applications. The motivation for this work was to provide a plant model and gain a deeper understanding of the physical system to be used in model-based development of a semi-active control methodology for vibration suppression. The work presented here is limited to the modeling aspect of the system.
