Abstract
The work is devoted to study of the effectiveness of the algorithm for controlling the synchronization of the rotors of a vibration unit (VU) with the digital implementation of the specified algorithm. A computer study of the dynamics of a two-rotor VU with a digital implementation of the control algorithm for rotor synchronization is carried out in the MATLAB environment. As a result the permissible sampling interval for calculating discrete control values using a zero-order extrapolator circuit was estimated. Also, using modeling, a comparative analysis of the efficiency of synchronization control in digital and analog implementation of the algorithm was carried out. It is shown that with an increase in the specified operating speed of the rotors, determined by the value of the energy H^∗ specified in the algorithm, the permissible value of the sampling interval decreases significantly. Comparison of the VU dynamics with the same values of the parameters of the synchronization control algorithm shows that the time of synchronization and the transient process in both cases are almost the same.
