摘要
实际研究中,大部分系统都可以近似为线性系统,因此对线性系统的研究非常重要。目前主要的研究方法有时域分析方法与频域分析方法,然而这些方法的应用比较繁琐和复杂,非常有必要设计专门针对线性系统的仿真软件,便于实际应用中对系统的控制。应用MATLAB语言设计的GUI仿真界面具有灵活、简便、修改方便等特点,可以随时修改线性系统的参数,并得到系统的时频域特性曲线与性能指标,使线性系统分析的工作量大大减少。
Most of the systems can be approximated to linear systems in actual research, so it is significant to study linear systems.At present the main research methods have time domain analysis method and frequency domain analysis method.However,the application of these methods are tedious and complex,so it is quite necessary to design special simulating software for linear systems to control systems in practical application.GUI interface designed by MATLAB language is flexible,easy,and conveniently modifying. It is also easy to modifying linear system parameters at any time and get the systems＇ time and frequency domain characteristic curves and performance index,thus make the workload of analyzing linear systems greatly reduced.
