Control strategy for car active suspension

Car suspension system is very important part of the passengers comfort and safety. In this article automotive active suspension with linear motor as an actuator is designed. H-infinity control is used to design the controller. This paper is focused on comparison of different controller designed for quart, half or full-car controller (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.
