摘 要:转动惯量辨识功能已经成为了高性能交流伺服系统的典型特征。基于加减速法的转动惯量测量方法过于依赖初始PID参数,辨识效果不佳。本文提出采用基于朗道离散时间递推算法的转动惯量辨识技术,提高转动惯量的辨识精度,同时加快辨识过程的收敛速度。 关键词:伺服系统;转动惯量辨识;朗道离散时间递推算法
Abstract: Inertia identification has become a typical character of high-performance AC servo system. Because the inertia identification based on accleration or decleration process is deeply depended on the intinial PID parameters, its result is not good. Inertia identification based on Landau discrete-time recursive was proposed in this paper to improve identification precise and to quick the process. Key words: servo system; inertia identification; Landau discrete-time recursive algorithm
