摘　　要：文章以某型号电动舵机(EMA)为例,建立数学模型,搭建了半实物仿真测试平台。其中,上位机采用dSPACE标准组件系统,在Simulink中建立仿真模型,控制界面采用ControlDesk软件设计,可实现在线调整控制参数,实时监控相关变量。在所搭建的半物理仿真平台上对该型号的电动舵机进行了模型辨识,结果表明,该仿真平台能够满足电动舵机的辨识要求,相对于正弦扫频信号,M序列的辨识效果更加令人满意。In this study, to take a certain electromechanical actuator (EMA) for example, its mathematical model is built. The simulation computer uses the dSPACE standard component system, the simulation model is developed in Simulink. The control interface is designed by ControlDesk software, the control parameters is adjusted online, and the related variables can be monitored in real time. The model identification for the EMA is researched in the HIL simulation platform. The results show that the simulation platform can meet the identification requirements of the EMA. Compared with the sinusoidal sweep frequency signal, the identification effect of M sequence is more satisfactory.
