The the related experimental courses and theory take many analysis and demonstration, which greatly enhance the students understanding of the theory of automatic control.Due to the experimental resources, simple facilities, instrument error and other reasons, the traditional experimental teaching impact the implementation of teaching.We study the principle of automatic control of the virtual experiment platform based on graphical user interface designed in MATLAB, which not only improves the efficiency of experiment teaching and the accuracy of the experiment, but also greatly enhance the enthusiasm of students and the ability to deal with problems.
