摘  要：伺服系统转动惯量的快速准确辨识是伺服驱动器控制参数自整定过程中的重要环节。伺服系统转动惯量主要有两种辨识方法, 分别是基于加减速的辨识方法和基于模型参考自适应的辨识方法。同时伺服最优控制参数都与转动惯量存在一定的联系，通过转动惯量的辨识，可以有效对伺服系统速度环控制参数进行整定，通过外部干扰也表明系统具有一定的抗干扰性能。

Abstract: The fast and accurate identification of inertia in servo system is an important part of the process in the servo drive control parameter self-tuning. There are two main identification methods with identification of inertia, named identification method based the acceleration and deceleration, and identification method based on the model reference adaptive. At the same time optimal servo control parameters are related to inertia, through the identification of inertia, parameters speed-loop control of servo system can be effectively tuned, through the external interference also shows that the system has a certain anti-interference performance.
Key words: inertia; the model reference adaptive; anti-interference performance
