1. Introduction
Hardware-in-the-loop (HIL) simulation has widely used among automotive industry, traffic control and
many other industry. HIL test became new trends in embedded system testing since they provide the
advantageous factor for the one who use it, the factor such as cost, safety, duration, and feasibility which
is to be sought for most industries. Not to miss researcher on robotics and unmanned vehicle area they
already use this type of simulation testing too. Like [4,9] that use HIL test for testing unmanned air
vehicle (UAV). Generally in HIL simulation test, a real environment condition did not applied during the
