A system and method for teaching experiments more specifically, the invention relates to a content-expandable linear position control teaching experimental system and method, including a computer, data acquisition and servo control processor, motor driver, DC motor, linear module, load module, grating displacement sensor, a magnetic grid displacement sensor and a limit switch sensor, the teachingexperiment system of the invention can be used as an open experiment platform in the electromechanical control direction, Expand a lot of relevant experiments, such as electromechanical system drive control experiment, time domain response experiment of typical input signal, frequency characteristic and open loop transfer function test experiment, position PID control experiment and system stability test experiment can help students understand the control process of mechatronics system, learn the basic theory of mechatronics system control, and cultivate students' ability of combining theory with practice.

Description

technical field [0001] The present invention relates to a teaching experiment system and method, more specifically a linear position control teaching experiment system and method with expandable content. Background technique [0002] "Fundamentals of Electromechanical System Control" is an important basic course for electromechanical integration majors. It is highly theoretical and abstract in concept. For most students, there is no physical teaching and experimental device to help understand theoretical knowledge, which will be difficult for many students. Without an intuitive understanding of the concepts, it will be difficult to master this course. At the same time, students in the direction of electromechanical control should have a further understanding of the combination of mechanics, electronics, and control of the mechatronics system through this course, especially a certain degree of understanding of the electromechanical parameters in the actual system; at present,...
