摘　　要：本文介绍了基于TMS320F28X的新型励磁控制系统。系统具有如下技术特色:⑴充分开发片上硬件资源,配合动态采样时间算法,实现整周期同步交流采样,从而提高系统动态品质和获取深度状态信息;⑵集自动控制和在线故障诊断于一体:充分利用DSP芯片强大的信号处理功能,实现了多诊断方法相融合的递阶故障诊断和容错处理;⑶基于eCAN总线的双机热备,大大提高了系统可靠性和可扩展性。A new type excitation control system based on 32 bits DSP is introduced in this paper. The technical features of this sys-tem 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 hierarchi-cal 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.
