机床结构传递函数在线识别的可辨识性

Identifiability of On-line Identification of Transfer Function of Machine Tool Structures

肯定了机床结构传递函数的在线识别应当采用闭环系统的辨识方法，讨论了机床切削闭环系统的可辨识性，给出了机床结构传递函数在线识别试验设计的原则。

It is affirmed that the method of on-line identification of transfer function of machine tool structures should be one for closed loop identification. The identifiability of closed loop machining systems is discussed. The principles of testing design are given for on-line identification of transfer function of machine tool structures.
