THE REAL TIME EXTENSION OF THE VIRTUAL TEST BED

This paper presents a Real-time simulation system with a hardware-in-the-loop (HIL) architecture. In particular, it demonstrates the possibility of executing Real-time HIL simulation by using the Virtual Test Bed (VTB)[1]. The Real-time Application Interface (RTAI), freeware providing the ability to make the Linux kernel fully preemptive and deterministic, is used to create a hard Real-time system clock. Based on that, a Real-time Linux simulation system is developed. By using this freeware platform, the authors extended the possibility of the Virtual Test Bed (VTB) to Real-time applications (RTVTB). Block Diagram Solver, one specific VTB solver, is used in the system. A commercial DAQ board (Advantech PCI-1710) is applied for the input/output interface between the Real-time simulation environment and the control hardware. Comedi is used to drive the Advantech PCI-1710 board. An Infineon C167CR 16-bit Microcontroller is applied as the control hardware of the HIL simulation. Finally, simulation results are presented and analyzed.
