This paper studies order reduction issues for a vehicle active suspension system throughout its modelling, H-infinity controller design and controller refinement. Computer simulations demonstrate that an H-infinity controller for a full active suspension can be significantly reduced to nearly one third of its full order, while the active suspension performance is only slightly degraded. As a by...

The main objective of designed the controller for a vehicle suspension system is to reduce the discomfort sensed by passengers which arises from road roughness and to increase the ride handling associated with the pitching and rolling movements. This necessitates a very fast and accurate controller to meet as much control objectives, as possible. Therefore, this paper deals with an artificial i...

In rail vehicles, air springs are very important isolating component, which guarantee good ride comfort for passengers during their trip. In the most new rail–vehicle models, developed by researchers, the thermo–dynamical effects of air springs are ignored and secondary suspension is modeled by simple springs and dampers. As the performance of suspension components have significant effects on r...

The current design of vibration energy recovery system for vehicle suspension does not analyze the under different road conditions, resulting in system's low ratio, efficiency, and utilization. Therefore, this paper, based on ultrasonic sensors is proposed. sensor used to obtain information vehicle, smooth uneven roads analyzed according obtained information. According analysis results, complet...

The value of a self-tuning adaptive semi-active control scheme for automotive suspension systems is discussed in this paper. current vehicle system uses fixed-coeffcient springs and dampers. ability to provide good road handling improve passenger comfort usually valued. Passive allows you choose between these two options. Semi-Active suspension(SAS), on the other hand, can both by manipulating ...
