In this paper, the levitation control of a hybrid-excited magnetic levitation (maglev) vehicle is presented. Both electromagnets and permanent magnets are used to levitate the vehicle. The nominal load is levitated by permanent magnet and the current consumption for stable levitation can be reduced. In order to guarantee the tracking performance, the proposed controller is based on the state feedback...
This paper deals with the design and analysis of a hybrid-excited linear synchronous motor (LSM) for magnetically levitated vehicles. On the basis of three-dimensional (3-D) finite-element analysis, this paper predicts levitation force and thrust characteristics according to design parameters such as airgap length, magnet size, and input current, etc. And then, a static force tester for LSM has been...
This paper deals with the zero-power control of magnetic levitation (maglev) vehicles that use permanent magnets as well as electromagnets for levitation. The nominal load is levitated by permanent magnet and the current consumption for stable levitation can be reduced. In order to guarantee the tracking capability, the proposed controller is based on the state feedback controller and modified to...
When considering vehicles as communicating mobile nodes, two existing and independently-developed technologies are combined- IP mobility solutions and VANET routing protocols. Particularly, the handover of the vehicle between VANETs is supported by Mobile IP(MIP). MIP has the problems of which are long latency time, triangle routing, and packets loss. So, we propose a new scheme of global mobility...
