Abstract

The invention relates to a Matlab-oriented DC motor speed control teaching experiment device. An Arduino development board is used as an interface for a control system to communicate with Matlab. Through optimized design of a DC motor speed control system, the device has become a complete, simple and low-cost teaching experiment and algorithm verification platform. By controlling the running status of a DC motor in a real-time and direct manner, students are enabled to have an intuitive understanding of the practical effect of a control algorithm and have a comprehensive and substantial understanding of the basic principle of a closed-loop control application system. The device, which is used as a simple, fast and low-cost experiment platform for theory teaching, plays an important stimulating role in improving the quality of teaching and strengthening students' understanding and design of a control theory and a control algorithm. The device is implemented on a bread board, is easier for beginners to use, and is of very high practicability. Moreover, the functional modules can also be used in other control devices, and are of high commonality.

Description

technical field [0001] The invention relates to an automatic control teaching experiment device, and more specifically relates to a Matlab-oriented DC motor speed regulation control teaching experiment device. Background technique [0002] "Automatic Control Theory" is a highly theoretical course and an important technical basic course for automation majors (independent undergraduate section), which is inseparable from engineering practice. It is not only the deepening of basic courses to professional courses, but also the theoretical basis of professional courses. The task of automatic control theory is to study the motion law of variables in the automatic control system and the possibility and way to change this motion law, for the construction of high-performance The automatic control system provides the necessary theoretical means. For most students, there is no intuitive physical teaching device to link theoretical knowledge, and it will be difficult to fully master th...
