VIBRATION UNIT CONTROL OF PASSING THROUGH RESONANCE WITH CONSIDERATION OF THE DYNAMICS OF ELECTRIC DRIVES AND ELASTIC CONNECTIONS
The problem of controlled passage through the resonance zone for mechanical systems with several degrees of freedom is explored. A control algorithm based on the velocity gradient method and estimation of the slow-motion near-resonance frequency (Blechmann frequency) has been developed. The results of modeling for a two-rotor vibration unit model, taking into account the elasticity of cardan shafts and the dynamics of the DC electric drive system, are presented, which illustrate the effectiveness of the proposed algorithms.
