摘要: Section 1.1 is devoted to the study of dynamical processes in electric circuits. It includes derivations constitutive relations elements circuits (capacitors, inductors) and describes current voltage sources Kirchhoff’s law. 1.2 deals with mechatronic systems (transducers) electromagnetomechanical circuit. In Sect. 1.3, dynamics control a mass levitating magnetic gravitational fields discussed. Two cases numerical are considered verified experimentally. 1.4, combined analytical analyses vibrations string-type generators carried out. The string governed by PDE, whereas an amplifier ODE time delay. generated on ends depends both electromagnetic induction vibration speed. An averaged set equations derived numerically studied. Finally, Sect.1.5, 2-DOF nonlinear rotor supported magnetohydrodynamic bearing investigated using perturbation analysis. modes corresponding vertical horizontal coupled. non-resonant case various resonant (with without internal resonance) considered. Frequency-response curves obtained. When amplitude external harmonic excitation near one natural frequencies system experiencing resonance, saturation phenomenon occurs.
