Abstract

The invention discloses a motor speed control experiment platform based on a rapid control prototype and a method. The experiment platform comprises an NI PXI platform, a frequency converter, a three-phase asynchronous motor, a Hall sensor and a tachometer. The NI PXI platform is used for sending signals to the frequency converter through an output terminal. The frequency converter is used for regulating the rotational speed of the three-phase asynchronous motor, the Hall sensor is used for detecting the rotational speed of the three-phase asynchronous motor, and the tachometer is used for displaying the detection data of the Hall sensor and sending the detection data to the input terminal of the NI PXI platform. The NI PXI platform includes NI host, data sending end and data receiving end. The data sending end is connected with frequency converter, and the data receiving end is connected with tachometer. The invention obtains the deviation between the actual speed and the preset speedby comparing the actual speed and the preset speed of the three-phase asynchronous motor in the NI host computer, observes the influence of the three parameters on the experimental simulation resultby adjusting the PID control parameters, and is beneficial for students to deeply grasp the basic principle of the PID control method.

Description

technical field [0001] The invention relates to the technical field of a rapid control prototype semi-physical simulation teaching experiment platform, in particular to a motor speed control experiment platform and method based on a rapid control prototype. Background technique [0002] With the advent of the "Internet +" era, advanced information technology, rich online teaching resources and diverse teaching methods have brought great impact and challenges to traditional teaching methods, coupled with the social demand for applied talents This requires colleges and universities not only to impart basic theoretical knowledge to students, but also to continuously strengthen the cultivation of students' practical ability and innovative ability. Most of the traditional motor control teaching experiment methods only pay attention to the basic theory teaching in the classroom, and do not pay attention to the experimental teaching; a small number of courses have experimental teac...
