Real time simulator for railway traction and auxiliary power unit control applications

摘要

This paper mentions about applications of a real time simulator (RTS) for railways traction and auxiliary power unit (APU) control. The RTS allow us to examine the control algorithm before on-site examination. This improves the efficiency of control algorithm development. Mathematical models of traction control system and APU are programmed in a field programmable gate array (FPGA) in order to realize the simulation precision of 1 microsecond. Various examples of real-time simulations are included in this paper to confirm the effectiveness of the RTS.
