本软件主要用于结构的时域试验模态分析，包括单输入单输出，单输入多输出和多输入多输出程序设计。传统的模态分析软件大多是基于频域分析方法，需首先对采样信号进行Fourier 变换。本软件使用实测时域信号，无需Fourier变换，可以避免由于信号截断而引起泄露、出现旁瓣、分辨率低等问题对辨识精度的不利影响。此外，节省了计算机运算时间，可以对实际工况状态下的结构进行在线参数识别。(This software is mainly used for the structure of time-domain experimental modal analysis, including single-input single-output, single-input multiple-output and multiple-input multiple-output programming. Traditional modal analysis software are mostly based on frequency domain analysis, needed first sampled signal Fourier transform. The software uses the measured time-domain signal without the need for Fourier transform, avoid truncated because of the signal caused by leaks, there sidelobes and low resolution of the issue of adverse effects on the identification accuracy. In addition, the savings in computing time, to the actual condition of the structure of the state-line parameter identification.)

说明：  异步电机的精确控制和速度辨识是交流传动系统中重要问题。该仿真模型在异步电机的数学模型、矢量控制原理及速度辨识算法的基础上，利用Matlab/Simulink仿真软件中SimPowerSystems模块，构建了基于MRAS无速度传感器的异步电机矢量控制系统。(The precise control and the speed identification of AC motor are the very important issues on AC drive system. In this paper, on the basis of analyzing the mathematical model of AC motor, the principle of vector control and the algorithm speed identification, the speed sensorless vector control system of induction motor based on MRAS is constructed on SimPowerSystems modules of Matlab/Simulink simulation software. )
