摘　　要：针对移动电站电源制式的多样化,设计了一种以STM32F103ZET为控制核心的同步电机通用型励磁控制系统,设计了低剩磁电压起励电路,满足了不同剩磁条件下的起励要求;针对独立电力系统的电压、频率波动较大造成采集精度下降的问题,引入了锁相环电路,实现了同步采样,提高了采样精度;采用参数自整定模糊PID的控制策略,通过IGBT功率器件进行励磁电压的PWM调节。实验结果表明,可以满足通用化的要求,具有较好的动、静态性能,调节速度快,完全符合规定的性能指标。According to the diversity of mobile power supply system, an general type excitation control system of synchronous generator by using STM32F103ZET as the control center is designed,the design of low remanence voltage exciting circuit,adapt to the different conditions of the excitation requirements of remanence;For the independent power system, the voltage and frequency fluctuation caused by the falling of the acquisition accuracy, the PLL circuit is introduced to realize the syschronous sampling, which can improve the accuracy of the acquisiyion; Using the control strategy of fuzzy PID based on parameter self-tuning. The excitation voltage was controlled by power IGBT device. The experimental result indicated that it meets the requirements of equipment universal,and it has better dynamic, static performance, fast regulating speed, fully meet the requirements of the performance index.
