Teaching experiment system for automatic control principle

Abstract

The invention discloses a teaching experiment system for the automatic control principle, and belongs to the field of teaching experiment system designing. The teaching experiment system comprises a mechanical loading device, a lower computer, two displacement sensors and an upper computer. The lower computer comprises a CPU and an A / D conversion module, wherein the upper computer, the CPU, the mechanical loading device, the two displacement sensors and the A / D conversion module are connected in sequence; the two displacement sensors and the CPU are respectively connected with the A / D conversion module. According to the teaching experiment system, as a mechanical device is adopted to form a typical second-order system serving as a controlled object, the operation state of an actual system under different controlled conditions can be observed by students, and intuitional instruction and theory and practice combination are facilitated. Besides, the teaching experiment system has important significance for improving laboratory teaching quality and strengthening understanding of the control theory and control engineering for the students.

Description

technical field [0001] The invention belongs to the field of teaching experiment system design, in particular to an automatic control principle teaching experiment system. Background technique [0002] "Automatic Control Principles" is a professional basic course for automation majors and related majors in higher engineering colleges, and occupies an extremely important position in the professional curriculum system. But at the same time, because it is a highly theoretical engineering science, the system analysis and design methods involved in the course are complex, and it is difficult for students to master them. Therefore, the effect of the experimental teaching link is very important for students to master theoretical knowledge and improve the teaching of this course. Quality all plays a very important role. [0003] The traditional teaching experiment methods commonly used at present include: simulation implementation based on MATLAB, simulation implementation based on...

AI Technical Summary

Problems solved by technology

However, the experimental content of the simulation experiment box is mainly simulation experiments. Control simulation experiments such as typical link simulation, system calibration, and system time / frequency domain analysis are carried out by connecting analog circuits. There is no experimental equipment for controlling the actual control object, and it lacks intuition and operability

The characteristic parameter adjustment of the control object is mainly based on the circuit parameter adjustment. It is difficult for students to understand the engineering application of the automatic control principle, and the theoretical explanation is not closely combined with the engineering practice.
