Abstract:
This article proposes a disturbance observer-based event-triggered
H
∞ controller for a semi-active seat suspension that equips an
advanced electromagnetic damper (EMD) system. Automated driving is one of the
leading technologies of the automotive industry. However, automated vehicles
(AVs) may increase the incidence of motion sickness (MS) and deteriorate motion
comfort. This article investigates a semi-active seat suspension system and an
advanced controller to improve the motion comfort of AVs. The disturbance force
of the seat suspension has considerable influence on the system dynamic, and
applying a constant model to describe the real-time disturbance force is
unreliable. Therefore, a disturbance observer is designed to estimate the seat
suspension disturbance force, and it is used to compensate the controller. The
Bouc-Wen model is selected to compare with the disturbance observer and validate
its effectiveness. Then an event-triggered H
∞ controller combined with the disturbance observer is proposed. The
performance of the proposed controller is validated with experiments.
Experimental results show that the proposed event-triggered H
∞ controller not only can save the communication resources of data
transmission but also can work as a filter to increase motion comfort.
