• Calculation of self and mutual inductances of the switched reluctance machine mathematical model.

  Publikacja

  • I. Mosoń
  • A. Wilk

  - Technical Electrodynamics - Rok 2006

  A mathematical model of the switched reluctance machine (SRM) in a drive system obtained using Lagrange's energy method and a method of calculation of self and mutual inductances of the SRM are presented in the paper. The self and mutual inductances are elements of Lagrange's function in generalised coordinates and have been calculated using the finite element method (FEM). Selected calculation results for the particular machine...

• Simulation of the switched reluctance drive system

  Publikacja

  • I. Mosoń

  - Rok 2005

  Switched reluctance motors (SRM), unlike other types of motors, for their application require a control system and the supply from a power electronic converter. A method of modelling and mathematical model of an SRM in a switched reluctance drive (SRD) system is presented in the paper. Modelling is based on Lagrange's energy method. Coefficients of the Lagrange's equation have been calculated using the finite element method (FEM)....

• Non-linear circuit model of a single doubly-fed induction machine formulated in natural axes for drive systems simulation purposes

  Publikacja

  • R. Strzelecki
  • A. Wilk
  • I. Mosoń

  - Rok 2008

  Mathematical modelling and a circuit model formulated in natural axes of a single doubly-fed induction machine, with the account of magnetic circuit nonlinearity are presented in the paper. Derivation of the model differential equations was based on Lagrange's energy method. State functions of magnetic elements in the model are non-linear and depend on all currents flowing in the machine windings and on the angle of rotor position....

• Forced Vibrations in a Dynamic System That Is Damped By a Mechanism Which Trans-Pass Through Its Singular Position

  Publikacja

  • K. Lipiński

  - Rok 2024

  The paper focuses on forced vibrations of a mechanical system. The system is composed of two structurally different parts: multibody modelled and finite elements modelled. To improve its numerical behaviour, author-proposed technique of tuning of modal properties is proposed. To combine the two sub-models, constraint equations are introduced and dynamics equations are extended with appropriate Lagrange multipliers. A slightly modified...

• Simulation of influence of the air gap asymmetryon voltage waveforms of a synchronous machine

  Publikacja

  • A. Wilk

  - Rok 2005

  Results of simulation of a synchronous generator with the air gap asymmetry characterised by eccentricity are presented in the paper. The Lagrange's energy method has been used in derivation of the model equations. Analysis of influence of the air gap asymmetry on characteristics of self and mutual inductances of windings, as well as analysis of induced voltage waveforms as a function of the air gap asymmetry have been performed....

• Mathematical modelling of the overhead contact line for the purpose of diagnostics of pantographs

  Publikacja

  • P. Kaczmarek
  • K. Karwowski
  • M. Michna
  • M. Mizan
  • A. Wilk

  - Czasopismo Techniczne - Rok 2016

  The overhead contact line (OCL) is the most effective way for supplying railway electric vehicles. The increase of the speed of the vehicles increases power consumption and requires ensuring proper cooperation of pantographs with OCL. The paper describes the novel mathematical model of the OCL system and the simulation results. The primary objective is a more accurate analysis to increase the reliability of the evaluation of monitoring...

• Variational principles for bound states of Schrödinger and Dirac equations allowing the use of discontinuous trial functions

  Publikacja

  • R. Szmytkowski
  • S. Bielski

  - INTERNATIONAL JOURNAL OF QUANTUM CHEMISTRY - Rok 2004

  We present systematic constructions of variational principles for energies of bound states of the Schroedinger and Dirac equations. The principles allow the use of discontinuous trial functions. The method employed is based on a generalized Lagrange procedure. Relationships between our variational principles and those available in the literature are established.
