Semi-physical simulation motor control and power electronic experiment device and experiment control method

Abstract

The invention discloses a semi-physical simulation motor control and power electronic experiment device and an experiment control method, and relates to the field of power electronics and motor control. The device comprises a computer installed with MATLAB / Simulink software, an HIL data acquisition card, a motor drive cabinet, different kinds of motors and a high-performance router. A user can write different control programs of power electronics and motor control in the MATLAB / Simulink software and an IP address of a host connected with controlled equipment is configured when the control programs are written, so that other computer hosts in a local area network can remotely control experiment equipment through the local area network, the problem that one computer can only control one experiment device in traditional experiment equipment can be solved, the experiment efficiency can be improved, and the purchase cost of the experiment equipment is reduced. Meanwhile, semi-physical closed-loop simulation can be formed by combining with an external hardware circuit so as to complete control experiments of various basic power electronics and different motors.

Description

technical field [0001] The invention relates to the fields of power electronics and motor control, in particular to a semi-physical simulation motor control and power electronics experiment device and an experiment control method. Background technique [0002] Power electronics is a subject that uses power electronic devices to control and convert electric energy. It is an interdisciplinary subject between the three major fields of electricity, electronics, and control. Moreover, the current undergraduate experimental teaching equipment is relatively simple, and the experimental content is less, often in the form of Verification experiments are the main focus, and few teaching experimental equipment take into account scientific research purposes, which cannot satisfy the school's cultivation of students' comprehensive, R&D, and advanced learning abilities. Thereby causing the user to be unable to bring into play the subjective initiative of oneself and creative thinking ther...

[0002]Power electronics is a subject that uses power electronic devices to control and convert electric energy. It is an interdisciplinary subject between the three major fields of power, electronics and control; and the current undergraduate The experimental teaching equipment is relatively simple, and the experimental content is less. It is often based on verification experiments. Few teaching experimental equipment takes into account scientific research purposes, which cannot meet the school's cultivation of students' comprehensive, R&D, and advanced learning abilities.

As a result, users cannot exert their subjective initiative and creative thinking

And for the traditional experimental equipment in colleges and universities, a computer host is generally used to match a set of experimental equipment, and the purchase quantity of experimental equipment is limited by the amount of the school. It is often necessary for several students to share one experimental equipment, thereby reducing the cost of students doing experiments. efficiency

In this way, when the experimental equipment is insufficient, the efficiency of the experiment will be reduced
