This work provides a new approach for modeling the electromagnets of magnetic levitation (Maglev) vehicle Transrapid intending to effectively and efficiently represent statics dynamics in frequency range relevant Maglev control design use mechatronic simulation models. It includes effects reluctances, fringing leakage flux, saturation, eddy currents. The follows systematic by setting up equivalent electric circuits, coupling equations using Ampère's circuital law Faraday's induction...
Abstract High‐speed Maglev is a cutting‐edge technology brought back into the focus of research by plans Chinese government for development new 600 km/h train. A Chinese‐German cooperation with industrial and academic partners has been established to pursue this ambitious goal bring together experts from multiple disciplines. This contribution presents joint work achievements CRRC Qingdao Sifang, thyssenkrupp Transrapid, CDFEB, ITM University Stuttgart, regarding in field high‐speed systems....
In this work, a nonlinear magnet model including magnetic saturation is proposed with focus on control design for magnetically levitated (Maglev) vehicle. It shown that the model's static characteristics corresponds measurements obtained from test bench, whereas standard models which neglect fail especially high currents. To consider nonlinearities of system directly in design, predictive scheme used controlling magnet's unstable dynamics. With highspeed application, algorithm adapted to...
Abstract A flexible and simplified method for the formulation of criteria optimization muliibody systems is presented using point- piecewise defined functions. These functions may lead to non-differentiable points discontinuous sensitivities. Their computation influence on convergence behavior an SQP-algorithm examined. The sensitivities are computed Automatic Differentiation method, which can easily be adapted a wide variety computer-evaluated gradients. application as well shown example...
Abstract The system integration of cross‐industrial networks in the Carbon2Chem ® project relies on numerical simulations. Hence, this study validates methanol synthesis loop models vs. measurements from a demonstration plant, focusing thermodynamic, kinetic, and dynamic aspects. plant can produce up to 500 L per week real blast furnace gases thyssenkrupp steel Duisburg. Despite its small size, it comprises recycle gas an original reactor tube 6 m length. After validation, simulation are...
For magnetic levitation transport systems with pillared tracks, detailed simulation models of the coupled system vehicle and guideway offer a valuable contribution to find tradeoff between stiff/heavy elements, required keep disturbances small for controller, low material consumption.This work provides novel model rigid multibody Transrapid maglev three sections moving along an infinite periodically elastic mapping two-dimensional heave-pitch motion bending elements.The is realized by...
