Abstract

Abstract: The problem of controlled passage through resonance zone for mechanical systems with several degrees of freedom is analyzed. The simulation results for two-rotor vibration unit illustrating efficiency of the control algorithm based on speed-gradient method are presented. The novelty of the results is in evaluation of the closed loop system performance when the electric drive dynamics are taken into account. An interesting fact is that for vibration unit model taking into account the electric drive dynamics the time of passage through resonance zone sometimes may be less than for the simplified model neglecting the drive dynamics.
