Self-tuning Control System Based on Virtual Instrument

Yinjuan Zhang

Abstract

We combine LabVIEW,a virtual instrument programming software,with MATLAB,a powerful mathematics software,in order to develop a set of excessive step-lagging self-tuning control system based on LabVIEW editing environment.Mixing LabVIEW programming with MATLAB and using the least square method to carry on the parameter identification and forecast the smallest variance model,a self-tuning control system is realized.It can be seen that the design capability of developing virtual instruments is improved with the combination of LabVIEW and MATLAB.
