MATLAB在数字控制器设计中的应用

随着对自动控制系统功能要求的不断提高，计算机控制系统的优越性也表现得越来越突出。现代的控制系统不管是简单的还是复杂的，几乎都是采用计算机控制。在设计计算机控制系统的数字控制器时，由于Z域计算的复杂性，已不能像连续系统那样可以靠手工的近似计算确定控制器和检验性能指标，必须利用某种计算机软件进行数字仿真。MATLAB非常适合做控制系统的数字仿真。该文介绍了在计算机控制系统中，利用根轨迹法设计数字控制器时，NATIAB软件的应用，包括绘制根轨迹及动态性能指标的检验等。

Application of Matlab in Digital Controller Design

These days. as the advance of the autocontrolsystem.the advantage of computer control sytem is standing out.Modern control systems no matter simple or difficult,most of them are controled by computer. Designing a digital controller,because it's difficult to calculate in Z field, we have to use some software to do digital emulation. MATLAB is suitable for the digital emulation of control system very much. We introduced the application of MATLAB in the computer control system,including protracting contrail,testing of dynamic capability guideline and so on.
