用sisotool实现经典控制系统的设计与仿真

sisotool是MATLAB中一个图形用户界面的设计工具,可用来分析和调整SISO反馈控制系统.文中介绍了MATLAB7.0.1中的控制系统工具箱所提供的sisotool,并用该工具设计了经典控制系统.导入系统的模型后就能自动显示根轨迹图和伯德图,用鼠标可以直接对屏幕上的对象进行操作,并且与sisotool动态连接的可视分析工具LTIviewer马上显示出设计结果,从而实现了经典控制系统的设计与仿真的可视化操作.示例表明,sisotool使得经典控制系统的设计变得更简便、更直观,给经典控制系统的设计带来更高的效率和更好的质量,具有广阔的应用前景.

Design and Simulation of Classical Control System Using Sisotool

The SISO Design Tool is a graphical user interface that facilitates the design of compensators for single - input, single - output feedback loops. The SISO design tool of Control System Toolbox of MATLAB7.0.1 is introduced firstly, and then the classical control system is designed using sisotool. After the models of classical control system are imported, the root locus and open - loop Bode diagrams can be drawn automatically. Using the mouse, the object can be manipulated directly on the screen, and LTI Viewer associated with SISO Design Tool will automatically update the response plots. So it can make the design and simulation of classical control system visual. The example shows that the sisotool makes the design of classical control system more simply and intuitively with higher efficiency and better quality, it has a wide application prospect .
