摘　　要：交流励磁发电机具有超越传统同步发电机和异步发电机的优良特性,在风力发电、抽水蓄能等变速恒频发电领域有着广泛研究和应用。该文利用模糊控制技术自适应能力强、鲁棒性好等优点提出了一种不依赖于交流励磁发电机精确数学模型的励磁控制方案,建立并详细分析了交流励磁发电机的全模糊解耦励磁控制模型。设计了全模糊励磁控制器并建立了双PWM变换器励磁的交流励磁发电机实验系统。实验结果展现了该文所提的智能模糊励磁控制策略具有优良的动静态控制性能,在提高交流励磁发电系统的参数自适应能力和鲁棒性等方面具有重要的实用意义。AC excited generator （ACEG） has more excellent characteristics than conventional synchronous and asynchronous generators, and it is widely developed in variable speed constant frequency （VSCF） generation area such as wind power generation and pumped storage power generation. Based on intelligent fuzzy control technology with good adaptive and robust capability, a new excitation control strategy for ACEG without accurate generator mathematical model is proposed in this paper. Full fuzzy excitation control model is established and analyzed in detail. An ACEG experiment platform based on dual PWM converter is established and it＇s good system performance is validated through experimental research. The experiment results show that fuzzy excitation control strategy has good static and dynamic performance and has importantly practical value for improving adaptive parameter capability and robustness of ACEG system.
