Abstract:As a critical tie between power and electronics of electric drive system for urban rail transit vehicle, traction control system is one of the most important equipment. Its characteristic of rich interfaces, complex logic and control algorithm, and onerous communication tasks, makes the simple control structure not suitable. A new control structure based on dual DSPs and FPGA is represented in this paper, which fully make use of the signal processing ability of DSPs and high speed parallel calculation ability of FPGA. The hardware and software structures are also given, as well as the debug software and languages of C/C++, very high speed integrated circuit hardware description language(VHDL) and graphic languages, that completely finish the multi-task and multi-rate control. The real systems have been fixed on the traction systems of subway and light rail vehicles, and the perfect performances validate the feasibility and rationality.
