交流伺服系统实时惯量辨识方法综述

摘要

交流伺服系统的参数实时辨识是实现高性能控制的前提.其中,转动惯量是最为关键的参数,其辨识值是控制器参数整定的基础,保证了系统的动态性能.近年来实时惯量辨识技术获得国内外学者的广泛关注并取得了大量的研究和应用成果.文章在此基础上,综述了针对单惯量和双惯量系统模型的实时惯量辨识方法及取得的最新研究进展,分析了各种方法在工程领域的应用.总结现有研究成果及亟待解决的问题,并对将来的研究方向进行了展望.%Real-time identification of AC servo system parameters is the prerequisite for high-performance control. Among them, motor inertia is the most critical parameter, which value is the basis of controller pa-rameter setting and to ensure the dynamic performance of the system. In recent years, real-time inertia iden-tification technology has been widely concerned from domestic and foreign researchers and has made a lot of research and application results. This paper reviews the real-time inertia identification methods for single in-ertia and dual inertia system models and the latest research progresses, analyzes the application of various methods in engineering field. Summarize the existing research results and problems to be solved urgently, and prospect the future research direction.
