伺服系统辨识的仿真与实现

介绍了一种机电伺服系统的辨识装置。针对一类伺服系统设计了完整的软硬件平台。阐述了相关辨识法与最小二乘法的基本原理以及其在伺服系统辨识中需要注意的相关环节。重点解决了应用M atlab系统辨识工具箱和其他仿真工具实现时的所有问题。将整个辨识工作模块化,从而得到一种简洁通用的软硬件辨识平台。并成功地应用COR-LS辨识方法得到了一个中功率伺服系统的传递函数。通过与实际系统模型的比较分析证明,该平台对于中功率伺服系统辨识结果非常令人满意。

Simulation and Implementaion of an Identification Set on a Servo System

An identification of a servo-system is studied in this paper.All the software and hardware of the system has been designed a class of servo-system.The COR-LS solution and correlative process that should pay attention to was introduced.Resolved the problems of system identification toolbox and other simulation tool in matlab when used in system identification.By dividing the identification work into module,an universal and compact worktable was got.Finally,a medium servo-system is identified with COR-LS solution.According to the comparison with the real model,this worktable was satisfying when used in servo-system.
