OPTIMAL LQR CONTROL SEMI-ACTIVE SUSPENSION SYSTEM WITH HALF CAR MODEL

Abstract

Currently, the research and application of semi-active suspension system is conducted by many researchers and attracts many automakers attention on development. Many controllers for semi-active suspension system were given as adaptive controller, robust controller, fuzzy controller, optimal controller. However, there is always a conflict between two quality criteria (drive comfort and road holding). Therefore, in order to design a controller simultaneously satisfy two quality criteria, the idea of designing optimal control for semi-active suspension system of half car model is studied and discussed in the text of this articel.
