This paper presents the design of a robust controller for a vehicle air suspension system using Quantitative Feedback Theory (QFT). This study is primarily focused on control of linearized active air suspension system. For the purpose of simplicity, the dynamics of the air suspension system is modeled using a simple 2-DOF quarter car model. Uncertain dynamic system with different working condit...

The main role of a car suspension system is to improve the ride comfort and road holding. The traditional spring-damper suspension is currently being replaced by either a semi-active or active suspension system, because, passive suspension system cannot give better ride comfort and handling property. In order to improve the capability of active suspension systems, a robust Adaptive B-spline Neu...

Primary suspension is the term used for suspension components connecting the wheel assemblies of a vehicle to the frame of the vehicle (Fig.1). This is in contrast to the suspension components connecting the frame and body of the vehicle, or those components located directly at the vehicle’s seat, commonly called the secondary suspension. Usually a vehicle contains both primary and secondary su...
