Active Suspension - Case Study on Robust Control

Authors: Kruczek A., Stříbrský A., Honců J., Hlinovský M.


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.

Keywords: Robust Control, linear motor, active suspension
