中文摘要:

      多电/全电飞机的关键技术之一就是飞控系统中的机电作动系统设计。在Ghosh和Bhadra所建立的电机键合图模型基础上，根据机电作动系统的原理和结构，应用功率键合图理论对机电作动系统各部件进行了研究，在此基础上建立起了机电作动系统的统一扩展键合图模型，并利用现有键合图软件对系统进行了仿真和分析。仿真结果符合预期的设计要求，为机电作动系统的优化设计提供了依据。

英文摘要:

      Based on the model of the bond graph of motor established by Ghosh and Bhadra,a unified expansion bond graph model is presented for the electromechanical actuator (EMA) system according to the principle and structure of the EMA as well as power bond graph theory.Meanwhile,simulation for the dynamic characteristics of EMA conforms to the requirements for intended results,which has presented foundation for optimization.
