【摘要】 机电作动系统是通过控制电动机或电器的运行直接或间接地控制负载的运动,实现控制目标的位置伺服控制的一类系统的总称。针对飞行器用机电作动系统,概述了其应用概况、结构的演化过程、关键技术的发展过程,并就机电作动系统的发展动态做了介绍。在此基础上,提出了飞行器用机电作动系统的研究和发展的一些建议。更多还原

【Abstract】 The electromechanical actuator (EMA) represents such a class of position servo systems, which directly or indirectly control the motion of load by servomotors or electrical devices. This paper summarizes the application, the history of structure evolvement and the key technology development of EMA, and introduces the developing trends of EMA. Based on the summaries and analysis, some suggestions are presented on future EMA research and development in the application to aircraft.更多还原
