In this paper, we consider a continuous version of the convex network flow problem which involves the integral of the Euclidean norm of the flow and its square in the objective function. A discretized version of this problem can be cast as a secondorder cone program, for which efficient primal-dual interior-point algorithms have been developed recently. An optimal magnetic shielding design prob...

Maglev transportation system is become a hot topic for researchers because of the distinctive advantages, such as frictionless motion, low power consumption, less noise, and being environmentally friendly. The maglev system’s performance gets sufficiently influenced by control method magnetic levitation dynamic performance, which critical component system. Magnetic Levitation System (MLS) group...

We describe the Phase-Space Nonlinear Control Toolbox, a suite of computational tools for synthesizing and evaluating control laws for a broad class of nonlinear dynamical systems. The Toolbox comprises computational algorithms for identifying optimal control reference trajectories in the phase space of dynamical systems and experimental methods for evaluating performance of the control laws. T...

Abstract As an important bearing structure of maglev train, the connecting rod has high requirements for material performance. In this paper, according to structural capacity rod, finite element methodwas used calculate and analyze composite aluminum alloy under two working conditions, so as determine advantages in mechanical properties provide theoretical support design rod.

As a new mode of transportation, maglev train has broad prospect. one the key technologies train, suspension control technology been hot research field. Maglev characteristics complex system modeling, strong nonlinear model, unstable open-loop system, and changeable working conditions. To date, widely used method is still design PID controller based on linearized model. However, with passage ti...

With rapid development of urban rail transit, maglev trains, benefiting from its comfortable, energy-saving and environmentally friendly merits, have gradually entered people's horizons. In this paper, aiming at improving the aerodynamic performance an train, optimization design has been performed. An improved two-point infill criterion adopted to construct cross-validated Kriging model. Meanwh...
