China Engineering and the teaching has yet to fully utilize the power of MATLAB, MATLAB existing books mostly as a computer application tool there, not with the specific disciplines of organic materials combined, MATLAB GUI interface design, will be teaching content according to a certain order of the structure, using simple language, a rich display screen in front of the students. not only improes the students interested in this program, also makes some of the more abstract concepts of the past and the process of teaching students to reflect difficult to understand and master the content, through iid, image of the method explained to the students, so that students more easily understand and grasp. MATLAB and the emergence of soling this problem, MATLAB based on its powerful calculation and graphics functions so as to sole the problem, The system is controlled teaching address the dull, abstract characteristics do.

而我国工科类的教学还未能充分利用MATLAB的强大功能，现有的MATLAB书籍大都作为计算机应用工具书出现，未能与具体学科的教材有机地结合起来，MATLAB中的GUI界面设计，将教学内容按照一定的结构顺序，用简洁的文字、丰富的画面展现在学生面前，不仅提高了学生学习本课程的兴趣，还使得一些比较抽象的概念和过去教学过程中学生反映难以理解和掌握的内容，通过生动、形象的方法向学生阐明，使学生更容易理解和掌握，而MATLAB的出现解决了这一问题，MATLAB基于它强大的计算和绘图功能从而解决了这一问题，本系统就是针对解决控制教学中的枯燥，抽象的特点而做的。
