中文摘要：

自动寻优控制是目前被广泛研究的转子自动平衡控制方法之一，但是该方法平衡精度有限且平衡时间较长，在实际应用中存在较大局限性。基于此，针对单平面双配重的转子自动平衡装置，提出了一种基于模糊控制原理的步长计算方法，并设计了变步长寻优控制算法，进而实现变步长寻优的转子自动平衡控制方法。通过自行设计并搭建的转子实验台及测控系统进行实验验证，实验结果表明该方法较传统的自动寻优控制方法在平衡精度和平衡效率上有明显改善。

英文摘要：

Automatic optimization control was one of the methods in rotor dynamic balancing which was studied extensively currently,but its balance precision was limited,and the balancing time was long,so there were many limitations in practical applications.Considering the above problems, aiming at the single-plane dual counterweight block dynamic balancing device,a rotor dynamic balan-cing control strategy was proposed herein,which calculated the step size by fuzzy control and comple-ted the balancing process by variable step size optimizing method.A self-designed rotor test rig was built with the measure-control system for experimental verification,and the results prove that the control strategy improves the balance precision and efficiency obviously compared with the traditional automatic optimization control method.
