摘要

这项工作致力于研究振动装置（VU）转子同步控制算法的有效性，以及指定算法的数字实现。在 MATLAB 环境中，通过转子同步控制算法的数字实现，对双转子振动单元的动态进行了计算机研究。结果估算出了使用零阶外推电路计算离散控制值的允许采样间隔。此外，通过建模，还对数字和模拟算法的同步控制效率进行了比较分析。结果表明，随着转子指定运行速度（由算法中指定的能量 H^∗ 值决定）的增加，采样间隔的允许值会显著减少。在同步控制算法参数值相同的情况下，对 VU 动态进行比较后发现，两种情况下的同步时间和瞬态过程几乎相同。

Digital control of the synchronous modes of the two-rotor vibration set-up

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.
