The spatial properties and local active control of road noise
The spatial performance of local active control systems depends on the correlation properties of the primary sound field. Previously this sound field has generally been assumed to be diffuse when simulating active control performance. In this study the spatial properties of the primary sound field due to road noise in a car were measured using the spectral density matrix calculated from the out...
متن کاملLPV design of adaptive integrated control for road vehicles ?
The paper presents a multi-layer supervisory architecture for the design of adaptive integrated control systems in road vehicles. The performance specifications are guaranteed by the local LPV (Linear Parameter Varying) controllers, while the coordination of these components is provided by the supervisor. Monitoring components provide the supervisor with information needed to make decisions abo...
متن کاملRoad-Frequency Adaptive Control for Semi-Active Suspension Systems
In this paper, a road-frequency adaptive control for semi-active suspension systems is investigated. The control aims to improve the vehicle suspension performance (ride comfort and wheel handling) for all frequency regions of road disturbances. In order to achieve this aim, the control law is extended from the conventional skyhook control, and the controller gains are scheduled for various fre...
متن کاملRoad Surface Management - Local Road Applications
A: INTRODUCTION The Wisconsin Transportation Technology Transfer Center (Transportation Information Center) has developed a roadway management program for Wisconsin local agencies. This system has been developed in cooperation with local road agency associations and the Wisconsin Department of Transportation. Wisconsin's pavement management system has evolved from a basically paper system devel...
متن کاملResearch on Adaptive Crossroads Control Model Based on Wireless Sensor Networks
Traffic information collection and traffic flow control around the crossroads are main topics of current traffic related research. The most commonly used method of traffic signal control at present is fixed-time control which only applies to small traffic flow circumstances with low efficiency. Therefore, we propose a new method which is an adaptive crossroads control model based on Wireless Se...
