Automotive active suspension - case study on H-infinity control

Abstract:- Automotive suspension system is important part of car comfort and safety. In this article automotive active suspension with linear motor as actuator is designed using H-infinity control. This paper is focused on comparison of different controller designed for quart, half or full-car model (and always used for “full ” car). Special attention is placed on energy demand of the whole system. Each controller configuration is simulated and then verified on the hydraulic quarter car test bed. Key-Words:- robust control, active vehicle suspension, linear motors, energy control
