A method of designing a linear current controller based on an H-type bridge chopper is presented with consideration of the impedance behavior and magnetic excitation requirements of the MR (Magnetorhelogical) damper system. Furthermore, parameters of the current controller affecting the performance of MR damper system are investigated. Then a dynamic model(More)
In view of the vehicle cornering or path changing under ultimate handling maneuver, a 4-DOF nonlinear vehicle dynamics model which takes the longitudinal velocity, lateral velocity, yaw rate and body roll angle as the state variables is presented. Based on the dynamic analysis, the method which using additional yaw moment produced by different longitudinal(More)
Wireless sensor networks (WSNs) have come to the forefront of the scientific community recently. Network lifetime, scalability, and load balancing are important requirements for many wireless sensor network applications. Utilizing sensor nodes' energy can maintain a prolonged network lifetime. Clustering sensor nodes is an effective technique for achieving(More)
A transit-stub P2PSIP architecture is proposed in this paper. In this architecture, heterogeneous P2PSIP overlays are interconnected in a decentralized approach provided by a transit overlay. A special SIP element, P2PSIP router, is designed to exchange SIP routing information and route SIP messages. Our architecture reacts to the change of route(More)
