摘要

本研究主要目的是針對乘客舒適性做探討。使用不同於前人所利用的控制法則，在此以可變結構系統理論中之虛擬根值法(virtual eigenvalue method)為基礎，應用於半主動式懸吊系統。此研究控制法則其中一部份利用虛擬根值法，設計出順滑向量，其另一部份的傳統狀態回饋控制，利用LQR(Linear Quadratic Regulator)，得出增益值，將兩結合為控制法則，應用於半主動式懸吊系統，此研究並與被動式懸吊系統做比較。
此研究利用Matlab / Simulink建構出四分之一車線性模型為此研究模型，並與傳統被動式懸吊系統在不同型態路面輸入下進行模擬，其後再探討加速度的問題。

The paper propses research of passenger ride comfort. The use of sliding mode control of virtual eigenvalue method for foundation be applied for semi-active suspension system. One of sliding mode control method is virtual eigenvalue method to design sliding vector, another uses LQR(Linear Quadratic Regulator) to design state feedback control, then combine them to become control method for semi-active suspension system. This paper what compares with passive suspension system.
The paper uses Matlab / Simulink to establish a quarter car model, and compares what with passive suspension in several road surfaces, then discuss acceleration problem.
