| Abstract: | Introduced in this paper is the microcomputer excitation regulation device which is based on DSP chip TMS320LF2407A. Furthermore, expounded are how to use the advantage of fast Fourier transform algorithm in DSP, how to conduct simultaneous sampling of voltage and current of generator's stator with ADS7864, and how to measure accurately the PWM output by use of PID and linear optimal excitation control. At the same time, expatiated is how to use the SCI-CAN interface to realize communication between multi-hosts and the upper controller. |
