[Abstract]: A new type excitation control system based on 32 bits DSP is introduced in this paper. The technical features of this system are as follows: 1.realizing period synchronous AC sampling, improving system dynamic quality and acquiring deep degree state information, by fully developing hardware resource on the chip and coordinating with dynamic sampling time algorithm, 2.integrating automatic control with on-line fault diagnosis. Fully employing the strong signal processing function of DSP chip, realizing hierarchical fault diagnosis and fault tolerant processing in multi diagnosis methods fusion 3.double controller standby based on eCAN bus greatly improving system reliability and expandability.
