The Design of Hardware-in-the-Loop Simulation Based on Electric-Drive´s Mathematical Model

This paper utilizes the hardware-in-the-loop simulation technology, researching on the locomotive electric signal, has designed the locomotive electric signal simulation installment and the locomotive movement transmission simulation test bench. This text in view of the primary capability parameters of AC-DC electric-drive system under the trainpsilas running state. Then makes a research in the ideal running characteristic, the adjusting characteristic, the speed regulation characteristic of electromotor with the theory of AC-DC electric-drive and establishes it mathematics model. The electric drive mathematical model can provide the locomotive running status for the test platform to come to the locomotive transmission characteristic simulation experiment.
