A measurement and exciting current digital control system of eddy current dynamometer was designed with C8051F040, which is microcontroller of silicon laboratories. The architecture and function of main module were introduced. The system hardware gross structure and software realization were explained, and control strategy and CAN controller structure were introduced in detail. Experimental results show that the system has the advantages of rational design, high reliability, high precision powerful function and modular architecture. It also could improve the reliability and expansibility of the control system.
