Solving Time-Dependent Optimal Control Problems in COMSOL Multiphysics

I. Neitzel[1], U. Prüfert[2], and T. Slawig[3]
[1]DFG priority program SPP 1253, Technische Universität Berlin, Berlin, Germany
[2]DFG research center Matheon, Technische Universität Berlin, Germany
[3]DFG Cluster of Excellence The Future Ocean, DFG priority progam SPP 1253, Christian-Albrechts-Universität zu Kiel, Kiel, Germany

We use COMSOL Multiphysics to solve time-dependent optimal control problems for partial differential equations whose optimality conditions can be formulated as a PDE. For a class of linear-quadratic model problems we summarize known analytic results on existence of solutions and first ... En savoir plus

[2]General Dynamics Electric Boat, Groton, CT, USA
[3]United Technologies - Pratt & Whitney, East Hartford, CT, USA

The determination of the modes of vibration of Functionally Graded-Metal-Ceramic Composite plates is important in practice in order to prevent undesired resonances in structural components. This paper describes the application of COMSOL Multiphysics® software for the determination of the ... En savoir plus

Implementation of COMSOL Multiphysics® in Simulink® S-Functions, Revisited

A.W.M. van Schijndel[1]
[1]Eindhoven University of Technology, Eindhoven, The Netherlands

COMSOL Multiphysics® has standard facilities to export models to SimuLink®. Normally, the standard export works well if the solvers, available in SimuLink, can handle the problem. However, if a model in COMSOL Multiphysics® needs special solvers, for example airflow or other non-linear ... En savoir plus

[1]Bulk Superconductivity Group, Department of Engineering, University of Cambridge, Cambridge, UK

This paper presents the electromagnetic analysis of an all-superconducting synchronous electric machine, focusing on AC loss calculations in high temperature superconducting (HTS) coils. The numerical analyses of two 3D models are shown, including the model of the machine and its HTS ... En savoir plus

Heat Propagation Improvement in YBCO-Coated Conductors for Superconducting Fault Current Limiters

D. M. Djokic[1], L. Antognazza[1], M. Abplanalp[2], M. Decroux[1]
[1]DPMC, University of Geneva, Geneva, Switzerland
[2]ABB Corporate Research Centre, Dättwil, Switzerland

YBCO Coated Conductors (CCs), used for applications in Resistive Superconducting Fault Current Limiters (RSFCLs), are known to have insufficiently high Normal Zone Propagation Velocity (NZPV) during quench events. The improvement can be made by enhancing the thermal conductivity of YBCO ... En savoir plus
