摘　　要：由于飞机三级式同步发电机存在CSD(恒速装置),增加了飞机重量,而且发电及容量不能做到很大。提出一种飞机串级式无刷双馈交流发电机系统,去掉了CSD,在发动机转速变化的同时调节控制绕组电流大小实现变速恒频的目的。论文在对串级式无刷双馈发电机定转子磁场进行分析、给出电压和转矩方程的基础上,针对串级式无刷双馈电机的高耦合、非线性和多变量时变性等特点,设计了矢量解耦控制器,实现控制绕组电压与电流之间的解耦,在Matlab/simulink环境下进行了仿真研究,结果表明:利用矢量解耦控制算法对无刷双馈发电机进行分析,实现了变速恒频发电;系统运行良好,具有较好的动态响应特性;所采用的方法是正确的、可行的。A cascade brushless doubly fed machine （CBDFM） system was prepossessed in the paper without con- stant speed device （CSD） to achieve the purpose of variable speed constant frequency at the engine speed variation by adjusting the current of the control winding of the generator. In the paper, based on the features of the CBDFM, such as, high coupling, nonlinear and multivariable time - varying characteristics, the CBDFM stator and rotor mag- netic field were analyzed, and the voltage and torque equations were given. Then, a controller was designed based on vector decoupling control to achieve the decoupling relation between the winding voltage and current. To be contin- ued, the generator simulation model was given and simulated in with Matlab/simulink. The results show that the sys- tem has good dynamic response characteristics and the method is correct and feasible.
