弹性支撑直线电机系统模型的建立方法

The Methods of Setting up the System Model of Iinear Motor with Elastic Support

根据弹性支撑直线电机的工作原理建立了系统的理论模型,通过仿真实验表明系统的理论模型与实际模型的频响之间存在较大的偏差。为了得到更精确的数学模型,本文设计了辨识实验,讨论了辨识实验中应采用的输入信号及辨识方法,利用辨识实验得到了直线电机系统比较精确的系统数学模型,最后对辨识实验中应该注意的问题进行了说明。

The system theory model is constructed first based on the principle of the linear motor with elastic support. A great difference of frequency response between the theory model and the practical system is indicated with simulation experiment. To get a more precise mathematical model, we design the identifying experiment and discuss the inputting signals and the identifying methods. A more precise mathematical model of the linear motor is acquired with system identification. The matters needing attention in system identification are given.
