A vector control scheme suitable for high-power electric locomotive applications is given. In order to realize this scheme, a control system based on dual-microcomputer structure of floating-point digital signal processor TMS320C31 and single-chip microcomputer 80C196MC is designed. The control system makes full use of TMS320C31 fast floating-point operations and 80C196MC PWM waveform generation capability. The experimental results show that the dual-microcomputer system used in this paper has good real-time performance, can accomplish complex operations in vector control and generate SPWM modulated signals, and can perform reliable data exchange among subsystems
