【摘要】 为了提高双电机同步控制精度,在分析常用的同步控制策略基础上,提出了基于PID参数调节的偏差耦合控制策略。分别在以PXI控制器、NI运动控制卡构建的双伺服电机实验系统与单轴柔性冷弯成型机组的变截面机组上,以图形化编程语言Lab VIEW为软件工具,通过大量实验研究,分析比较了不同补偿方式的同步控制策略对伺服系统同步精度的影响,进一步验证了所提出的PID偏差耦合控制策略的合理性与适用性,提高了双电机同步控制的精度,同时满足了被控对象高精度的要求。更多还原

【Abstract】 In order to improve the synchronization precision of dual motor,the PID deviation coupling strategy is presented based on the analysis of common synchronization control strategy. By lots of experimental researches comparing synchronization precision of different control stategies,the rationality and applicability of the proposed PID deviation coupling strategy has been verified to improve the synchronization precision and satisfy the high control precision demand of the devices. All the experiments are compeleted on the dual servo motors test system and flexsible-rollforming unit respectively,whose control systems are constructed by PXI controller and NI motion control card,and graphic programming software Lab VIEW.更多还原
