摘　　要：在综合分析谐波励磁无刷同步发电机励磁控制系统的基础上,对其励磁控制策略进行了研究,开发了一套基于DSP(TMS320F2812)控制的新型柴油发电机励磁控制系统,该系统采用参数自适应模糊PID控制励磁,选用交流采样方式实时检测各信号的瞬时特性,系统仿真结果以及在1台25 kW工频柴油发电机上的试验结果证明了该控制器具有较好的电压调节特性,系统稳态和暂态性能完全满足发电机对励磁系统的要求。According to the general analysis of the excitation control system of the harmonious wave excitation brushless synchronous generator and its characteristics,a new type of diesel generator excitation control system based on DSP（TMS320F2812） was designed.An adaptive fuzzy PID control of excitation is used in this system.To detect the transient characteristics of the signals in a timely manner,AC sampling was applied.The system simulation results and the testing results from a 25 kW diesel generator（50 Hz） can prove that the voltage regulation characteristics of the excitation control system are very well,and both the steady-state performance and the transient performance of the generator are also good.
