Creating hardware-in-the-loop system using virtual instrumentation

In this paper we present a virtual instrument used to study the dynamics of systems through modeling and hardware-in-the-loop (HIL) simulation. For a D.C. motor is made, in Matlab environment, the mathematical model and this is included in virtual instrument like a Matlab script. The same virtual instrument, through PCI-6024E data acquisition card, ensure comparisons on front panel between results obtained by simulation with measured values of their.
