A Clock Synchronization Method for Multi Platform Combined Electric Drive Vehicle Real Time Simulation System

摘要

In order to realize the clock synchronization function of dSPACE real-time simulation platform, RT-LAB simulation platform, Vortex real-time dynamic simulation system and hardware controller, etc, a hybrid clock synchronization method is proposed in this paper. The master clock server output includes IEEE1588-2008 network clock synchronization signal and second pulse signal. Based on IEEE1588 network clock synchronization signal, the clock synchronization between the master clock and the Vortex simulation platform and the relay board is realized. And the clock synchronization between the master clock and the RT-LAB simulation platform is also realized based on the second pulse signal. In the mean time, the clock synchronization between dSPACE simulation platform and physical controller is realized by FPGA relay board.
