Abstract

A typical hardware-in-the-loop (HWIL) lab normally integrates a wide array of digital equipment, each driven by its own internal oscillator. While the various equipment designers may strive to utilize high-precision oscillators in their products, if no synchronization scheme is employed, then time-base drift between the various HWIL components is inevitable. If real-time communications between components is required, such as between the motion simulator controller and the simulation (host) computer, this time-base drift, exacerbated by timing jitter in the communication channel and each component's internal processing loop, can degrade the simulation fidelity. By designing the motion simulator controller to synchronize to an externally provided, facility-wide, standards-based site timing reference such as the Global Positioning System (GPS), the relative time-base drift can be completely eliminated. This paper discusses the advantages of this approach for improving HWIL simulation performance.
