非线性时变系统的辨识方法的研究

传统控制系统的被控对象多是考虑到线性时不变系统,由于工业的高速发展,控制系统面临着巨大的变化,被控对象呈现出非线性、时变、时延和外界干扰的系统,并且系统的模型不容易被确定,因此人们首先必须对系统进行辨识,确定系统的模型,才能进行有效地控制。文章主要对辨识的方法进行研究,然后给出辨识的方法和步骤,最后辨识的仿真结果。

Nonlinear time-varying system identification method

The traditional control systems to the controlled object to the linear time-invariant systems which faces enormous changes due to the rapid development of industrial control systems,the controlled object showing a nonlinear,time-varying delay and disturbance system and the system model is not easily determined,we must first identify the system to determine the model of the system in order to effectively control.This article mainly on the identification method,and then gives methods and steps of identification,the simulation results of the final identification.
