Direct current motor control teaching experiment system

Abstract

The invention discloses a direct current motor control teaching experiment system. The direct current motor control teaching experiment system includes an upper computer, a control processor and direct current motors; the upper computer automatically generates codes through MATLAB / Simulink model based design; the codes are downloaded to the control processor; the control processor transmits corresponding control signals to the direct current motors; the direct current motors are connected with detection sensors; the detection sensors return acquired detection signals to the control processor; the upper computer monitors the detection signals; the direct current motors include a first direct current motor and a second direct current motor which are connected with each other through a mechanical coupling transmission device; the mechanical coupling transmission device is connected with a baffle used for fixing the transmission shaft of the mechanical coupling transmission device; and the transmission shaft of the mechanical coupling transmission device is provided with a torque transducer connected with the control processor. The direct current motor control teaching experiment system of the invention has the advantages of simple operation and easiness in establishment and experiment verification. With the direct current motor control teaching experiment system adopted, a plurality of teaching experiment contents such as single-motor control and multi-motor control can be realized.

Description

technical field [0001] The invention relates to a direct current motor control teaching experiment system. Background technique [0002] With the development of electronic power technology and motor manufacturing technology, people's demand for automation is increasing day by day, the application field of motor is gradually expanding, and the control system of motor needs to be continuously developed. [0003] At present, most colleges and universities have set up courses such as motor control, automatic control, and mechatronics to teach motor-related knowledge and control methods. However, the scarcity and cost of relevant teaching and experimental equipment, as well as the complexity and repetition of the experimental process, lead to unsatisfactory teaching effects. [0004] In general, the current motor teaching experiment system has the following problems: 1) It is difficult to establish and verify the control algorithm, and it is necessary to write a large number of ...
