A Study on the Suspension System Modeling and Left Eigenstructure Assignment Control Design for Performance Improvement of an Automotive Suspension System

차량 현가시스템 성능 향상을 위한 현가장치 모델링 및 고유구조 지정 제어기 설계 연구

A conventional quarter-car suspension system is a single input system with one actuator. Thus, the performance enhancement for ride quality could be limited. In this paper, we propose a novel automotive suspension system for a quarter-car with two independent actuators to improve the control performance. The left eigenstructure assignment method for multi-variable systems has been applied to the proposed novel quarter-car model.
