摘　　要：目的为了提高凹版印刷机电子轴传动系统的可靠性以及控制精度,提出一种相邻交叉耦合滑模变结构多电机同步控制方法。方法基于相邻交叉耦合补偿基本原理建立相邻交叉耦合控制结构,并将滑模变结构引入到相邻交叉耦合结构中,通过饱和函数削弱抖振。结果仿真结果表明,改进型相邻交叉耦合多电机同步控制时系统在0.004 s便进入了稳定状态,在初期的0.002 s时间内同步误差出现了一定程度的波动,但从总体来看误差百分比很小。结论与其他控制策略相比,基于相邻交叉耦合系统的滑模变结构控制下其系统同步误差较小,具有更高的同步控制精度、更强的削弱抖振能力,同时系统具有较强的鲁棒性。The work aims to propose a multi-motor synchronous control method for adjacent cross-coupled sliding mode variable structure, so as to improve the reliability and control accuracy of gravure printing machine＇s electronic axis transmission system. Based on the basic principle of adjacent cross coupling compensation, the adjacent cross coupling control structure was established, and the sliding mode variable structure was introduced to the adjacent cross coupling structure. The chattering was weakened by the saturation function. The simulation results showed that, during the multi-motor synchronous control of improved adjacent cross coupling, the system entered a stable state at 0.004 s. Within the early 0.002 s, synchronization error was subject to certain fluctuation, but generally, the percentage error was very small. Compared with other control strategies, the system synchronization error is small under the control of sliding mode variable structure based on adjacent cross coupling system, with higher synchronization control precision and stronger chattering weakening ability. Meanwhile, the system has strong robustness.
