摘　　要：提出了一种抑制电动负载模拟器中多余力矩的新型方法,即位置伺服电动机电流前馈扰动补偿法。首先建立了电动负载模拟器的数学模型,然后讨论了加载对象角位移和加载电动机角速度前馈扰动补偿法的局限性,在此基础上提出了电流前馈扰动补偿法,并在Matlab中进行仿真,得到了很好的补偿效果。This paper puts forward a novel method for restraining the redundancy torque in the electric powered actuator -- the current of displacement servo DC motor forward compensation. The paper builds up the model of the electric powered actuator firstly, then discusses the limit of forward compensation using angle displacement and angle velocity, gives the current forward compensation based on that. At last, receives a very good result simulated in Matlab.
