Intelligent Control Design for Linear Model of Active Suspension System

摘要

Active suspension system poses the ability to reduce the traditional design as a compromise between handling and comfort by directly controlling the suspensions force actuators. This paper presents a linear model and control of a quarter-car active suspension system with unknown mass and road disturbance. The controller is designed to derive a control law and that achieves stability of the system and convergence that can considerably improve ride comfort and road disturbance handling. PD, Fuzzy PD, and Adaptive PD in order to use in active vibration control simulations. The designed controllers efficiency are examined using Matlab simulation. Finally, the designed controllers suitability are studied by comparing their performances in case of using different road profile functions.
