The vibration in the seat of vehicles can influence the level of comfort experienced by passengers and potentially introduce hazards to their wellbeing. To mitigate the effects of such vibrations, this article outlines the establishment of a control system specifically tailored for automotive seat suspension. Firstly, a dynamic model of the vehicle seat suspension was established. Subsequently, an adaptive approach to the vibration control was incorporated, which involved the design of a robust controller utilizing Youla parameterization. This controller was augmented into a globally stable controller set that can enable the utilization of an adaptive algorithm to fine-tune the Q parameter in real-time. Simulation and experimental tests were performed on the vehicle seat suspension to confirm that the proposed adaptive active vibration control approach is capable of efficiently mitigating both random and time-varying deterministic vibrations.
