中文摘要：

电动执行器以其优越的性能逐步替代气动和液压执行器,成为全电飞机最为重要的特征之一。采用电动执行器等功率电传技术能够有效提高飞行器的机动性、可靠性、维护性和续航性能,同时解决了液压系统其重量较大的问题。根据电动执行器控制系统的设计要求,建立了无刷直流电动机的数学模型,完成了电动执行器控制系统的硬件设计和软件设计。试验表明,控制系统能够稳定、可靠运行,可以满足系统设计要求。

英文摘要：

With its superior performance,electric actuator will gradually replace pneumatic and hydraulic actuators,and will become one of the most important features of the all-electric aircraft.The use of electric actuators such as power cable technology can effectively improve the mobility,reliability,maintainability and duration performance of the aircraft.And it can solve the problem of the heavy hydraulic system simultaneously.According to the design requirements of electric actuator control system,a mathematical model of the brushless DC motor was established and the hardware design and software design of the electric actuator control system were completed.The experimental results show that the control system is stable and reliable,and meets all design requirements.
