A Study on Automatic Control Principle Courseware Based on MATLAB

Abstract

The course of automatic control principle needs to draw a lot of curves, but actually it is difficult to achieve. In order to solve the problems that the diagrams of automatic control principle is difficult to draw and the knowledge is difficult to understand, this paper presents a kind of automatic control principle courseware based on VISUAL C++ and MATLAB hybrid programming. The hybrid programming methods of VISUAL C++ and MATLAB are discussed in this paper, then analyzes the concrete realization method of VISUAL C++ calling MATLAB engine. In order to get a friendly user interface, the courseware using VISUAL C++ to write GUI(Graphical User Interface) and related data processing utilizing the MATLAB control system toolbox. Through MATLAB engine, this courseware can easy to draw the Bode diagram, Nyquist curve, Root Locus diagram and so on. The courseware make full use of the advantages of VISUAL C++ and MATLAB, has a friendly GUI and basically achieved all functions of MATLAB, which are convenient for teaching. The courseware designed in this paper can help the student to study the principle of automatic control and can improve the study effect to a certain extent.
