An integrated device and method for DC motor speed regulation simulation and experiment

Abstract

The invention provides a DC motor speed regulation simulation and experiment integrated apparatus and a method. The apparatus includes a host computer unit, a control unit and a DC motor unit. Bidirectional communication between the host computer unit and the control unit are achieved through a USB communication module. The DC motor transmits a value of a real-time rotating speed to the control unit, and the control unit can control the rotating speed of the DC motor unit according to a calculated control value, wherein the control value is calculated according to a deviation value of a set value of the rotating speed of the DC motor and the value of the real-time rotating speed of the DC motor. By adopting the USB communication technology, the DC motor speed regulation simulation and experiment integrated apparatus can continuously transmit data acquired at a high speed to a host computer in real time, real-time communication between sampled data and the host computer can be continuously achieved with no loss at the sampling rate of 6 M / s. According to the method provided by the invention, after requirements of a simulation result are met through DC motor speed regulation system modeling and simulation research on a control algorithm, the control algorithm is directly transmitted to a controller to be carried out an experiment in the DC motor speed regulation simulation and experiment integrated apparatus, to greatly facilitate research on the control algorithm.
