多电机无轴传动同步控制策略

目的在印刷行业中,电子轴的同步传动控制得到不断发展,通过对其多电机的同步控制策略进行研究,提高其生产效率和产品质量。方法对比现有的几种同步控制方式,并应用Matlab对这几种不同结构进行建模和仿真研究。结果通过仿真分析,发现现有的同步控制方式抗干扰性能和同步协调能力都不太理想,而偏差耦合同步控制超调量大,且主要应用于2台电机的同步,因此,提出了一种结合虚拟主轴控制方式的相邻耦合误差多电机同步控制策略。通过仿真数据分析,其达到稳定的时间和超调量都比现有的同步控制小,且抗干扰能力也得到了提高。结论该策略可以提高多电机同步控制系统的同步跟随性能和抗干扰性能,增强多电机电子轴传动的同步协调控制能力。

Multi-motor Synchronization Control Strategy with Shaftless Drive

In the printing industry, synchronous drive control of electronic shaft has been developed continuously. This work aims to study its motor synchronization control strategy and further improve production efficiency and product quality. The existing synchronization control ways were compared. Modeling and simulation were conducted for these several different structures by Matlab. The simulation analysis showed that the existing synchronization control ways had no ideal anti-disturbance performance and synchronous coordination ability. However, relative coupling synchronization control had big overshoot and was mainly applied to the synchronization of two motors. Therefore, an adjacent coupling error control strategy combined with virtual spindle motor synchronous control method was proposed. According to the analysis of its simulation data, the stable time and overshoot it got were both smaller than those of the existing ways and its anti-disturbance performance was also improved. In conclusion, this proposal can improve the synchronous tracking performance and anti-interference ability of the motor synchronization control system and enhance the motor electronic shaft synchronous coordination control ability.
