摘　　要：机电作动器作为飞行控制系统的关键执行机构,其性能对系统输出动态响应具有重要影响.根据直驱型机电作动器的结构组成,建立包含永磁同步电机控制和行星滚柱丝杠非线性因素的系统仿真模型.研究了“i_(d)=0”电流矢量控制下的系统阶跃响应,结果表明:基于永磁同步电机三闭环伺服控制策略的系统在不同位置阶跃信号指令下均具有良好的动态性能.通过与文献的对比,表明该控制策略下的机电作动器仿真模型有效.As a key actuator in a flight control system,the performance of an electro-mechanical actuator has a significant impact on the dynamic responses of the system.Based on the structural composition of the direct-drive electro-mechanical actuator,a simulation model is established that considering the control of a permanent magnet synchronous motor and nonlinear factors of a planetary roller screw mechanism.The step responses of the system under the current vector control of“i_(d)=0”are studied.The results show that the system based on the three-closed-loop servo control strategy of the PMSM has the good dynamic performance under different position commands with the step signal.With the comparison to the literature,it is shown that the proposed simulation model of the electro-mechanical actuator under this control strategy is effective.
