Implementation of tracking system correction methods in the Simulink package from MATLAB CAD

Abstract

CNC equipment is flexible, versatile, and has high performance. The use of such equipment significantly changes the nature of production and makes it mobile, meeting the requirements for continuous improvement and updating of mechanical engineering products. However, CNC machines are quite complex, and their acquisition is associated with large financial costs, therefore, the problem of efficient use of CNC machines is a priority for most mechanical engineering enterprises and is inextricably linked with the need to write various programs. Variants of the implementation of sequential, parallel correction and feedback correction methods in the Simulink package from MATLAB CAD are proposed. When performing the work, customizable library blocks are used, which are available for students to access on the official website of the software manufacturer. Schemes for each correction method with a description of the included blocks are presented. The output of the results and the comparison of the obtained data is carried out using a software oscilloscope built into the package, which allows clearly understanding the difference between the schemes. A comparison is made on the example of various types of signals for the most objective assessment of the quality of signal correction by one method or another. The practical significance of the work is familiarization with the MATLAB CAD Simulink package and consideration of possible ways to implement these correction schemes, as well as availability of the same schemes for self-construction in this CAD. This work can be used not only for teaching students of higher educational institutions in the field of development, debugging and coding of electronic and radio-electronic devices in terms of describing the algorithm of their work, but also for organizing laboratory work on courses of disciplines related to this topic, as well as when creating and designing real devices in production. Familiarization and study of this programming language are conducted within the walls of one of the leading engineering universities of the Russian Federation, the Bauman Moscow State Technical University.
