Mitigating Time Delays: An Evaluation of Their Impact Using a Simulation Model of an Aircraft Power System Demonstrator Facility

The impact of time delays on emulation systems is examined through a simulation model of an aircraft power system demonstrator facility. The aircraft demonstrator uses hardware-in-the-loop (HIL) techniques to command a motor drive so that it emulates the dynamic characteristics of the shaft in an aircraft gas engine. As time-delay effects are inherent in the HIL test systems using industrial control platforms and communication systems, time-delay compensation techniques are required. Techniques to mitigate the time delay, or the effect of the time delay, are examined to enhance the accuracy of the gas-engine emulation.
