Real-time Digital Simulation of Control System with LabVIEW Simulation Interface Toolkit

In this paper, the virtual instruments software LabVIEW and its simulation interface toolkit are introduced at first. With visualization technology, LabVIEW can simulate an industry plant with better effect. The LabVIEW simulation interface toolkit (SIT) provides a seamless integration between MATLAB/Simulink software and LabVIEW. A method is presented to implement real-time digital simulation with no hardware-in-the-loop and a pure software real-time digital simulation example of a lever process control system using LabVIEW simulation interface toolkit is given. It can get better effect in teaching or training of industry process control system with minimal cost.

1 INTRODUCTION

With the development of computer technology, the drawbacks of traditional control system simulation system become more and more apparent. Putting virtual instruments software into control system simulation system will result in not only the cost reduction of the hardware, but also the enhancement of the teaching or training effect.
