中文摘要:
      针对航空三级式无刷发电机存在建压超调、调节范围有限、响应速度慢、难以满足高质量供电要求的问题,提出了基于改进分数阶控制(FOC)的多参数调压策略。通过增加励磁电流和负载电流反馈,实现多参数调压,改善动态性能。用改进分数阶PIλ控制器改善建压阶段的调节性能。将模糊规则引入分数阶控制器,使分数阶PIλ控制器兼具动态和稳态性能。为了有效验证所提方法的合理性,搭建了航空三级式无刷发电机仿真平台,进行了相关仿真分析。结果表明,与传统单参数反馈调压控制相比,所提方法能减少建压超调6.4%,在建压和突加、卸负载阶段,响应时间分别缩短了42.76%、37.01%、32.88%。
英文摘要:
      Aimed at the problems that as for the aerospace three-stage brushless generators, the built in voltage is overshoot, the adjustment range is limited, the response is low at speed, and difficult to meet the needs of high quality power supply,a multi-parameter voltage regulation strategy to improve three stage generators based on the improved fractional order control is proposed. Firstly, by increasing the excitation current and load current feedback,multi-parameter voltage regulation is achieved to improve dynamic performance. Second, the improved fractional order PI λ controller is used, and the controller improves the regulation performance during the build up phase. Finally, the fuzzy rules are introduced into the fractional order controller to make the controller have both dynamic and steady state performance. In order to effectively verify the rationality of the proposed method, an aerospace three stage brushless generator simulation platform is set up and the related simulation analysis are performed. The results show that compared with the traditional voltage control, the proposed method can reduce the construction pressure overshoot by 6.4%. In the construction pressure and sudden loading and unloading phases, the response time goes down by 42.76%, 37.01%, and 32.88% respectively.
