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MATLAB7.5中的控制系统工具箱所提供的isotool,并用该工具设计了控制器。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,从而实现了自动控制实验教学中的控制系统的设计与仿真的可视化操作。实例表明,sisotool使得控制系统的设计变得更简便、更直观,给自动控制实验教学带来更高的效率和更好的质量。
sisotool is a graphical user interface design tool in MATLAB that analyzes and adjusts the SISO feedback control system. This paper introduces the isotool provided by the control system toolbox in MATLAB7.5, and designs the controller with this tool. Import the system model will be able to automatically display the root locus diagram and Byrd diagram, the mouse can be directly on the screen object operation, and sisotool dynamic connection of visual analysis tools LTIviewer immediately show the design results in order to achieve automatic Controlling the Design and Simulation of Control System in Laboratory Teaching. The example shows that sisotool makes the design of control system easier and more intuitive, which brings more efficiency and better quality to automatic control experiment teaching.
