摘要
针对振荡问题,在工业控制系统中,电机与负载之间一般都是通过传动轴、齿轮或者联轴器等传动机构进行连接,然而传动机构有一定的刚度系数,并不是完全刚性的,因此电机和负载之间存在柔性传动。永磁驱动控制系统机械谐振抑制的综合设计是电机驱动领域的关键共性技术,对于提升永磁电机控制系统动态响应品质、提高系统安全性具有十分重要的意义。本论文主要研究使用陷波滤波器抑制机械谐振。针对实际系统中发生的机械谐振,需要研究运行过程中在线自动辨识其谐振特征方法,并根据谐振辨识出的谐振情况,自动配置陷波滤波器参数,实现自动抑制机械谐振的目的。
To solve the oscillation problem,in industrial control system,the motor and the load are generally connected through the transmission mechanism such as the drive shaft,gear or coupling,but the transmission mechanism has a certain stiffness coefficient and is not completely rigid,so there is a flexible transmission between the motor and the load,that is end oscillation.The integrated design of mechanical resonance suppression of servo drive control system is a key common technology in the field of motor drive,which is of great significance for improving the dynamic response quality and system safety of permanent magnet motor control system.In this thesis,notch filter was used to suppress mechanical resonance.In view of the actual mechanical resonance in the system,it is necessary to study the online automatic identification method of its resonance characteristics during operation,and automatically configure the notch filter parameters according to the resonance identified,so as to achieve the purpose of automatic suppression of mechanical resonance.
