With the development of human-beingpsilas civilization, public transportation has achieved great progress, but more attention has to be taken for children, old men, and other people who are not convenient to take public traffic, LFLRV (low floor light rail vehicle) has so many advantages that it is a very good choice in the city for these people. This paper describes the traction system of the first 100% LFLRV in China, including the design concept and control system realization. The traction control system is consisted of double-DSP (digital signal processor) and FPGA (field programmable gate array), and IFOC (indirect field oriented control) strategy, is used to control the traction motors, the synchronous problem and control method of independent wheels is also given. The simulation and experimental results validate the valid of the design and control of the whole system.
