The design of simple experiment system for automatic control system

Abstract

For the shortcomings high prices and big volume of traditional university laboratory experiment platform for automatic control principle, the paper designs the simple experiment system for automatic control principle based on double SCM system of AT89S52 and ATmega16 and virtual experimental software platform of LabVIEW. The system includes hardware and monitoring software interface of two parts. The system hardware part adopts the modular design concept, mainly including power module, signal generator module, basic experimental link module, control system link module and the data acquisition module. One signal generator and the data acquisition module contain lower level computer software programming. The upper level computer software is written by LabVIEW, and consists of serial parameters adjustment, display of data received, playback of data stored, and other functions. After the completion of the entire system design, the experimental result is consistent entirely with the simulation waveform of MATLAB through the step response for typical second-order oscillation link, and proves that the design of experiment system is feasible. © Springer-Verlag Berlin Heidelberg 2011.
