摘　　要：介绍了一种获得电动执行机构传递函数的新方法。该方法从分析电动执行机构的各个组成部分出发,最终推导出以供电电压为输入、反馈电压为输出的开环传递函数,并通过求解微分方程,提出了一种简单、快速确定执行机构传递函数参数的新方法,来求解该传递函数的参数。物理实验和Matlab仿真都表明,这种方法简单、便捷。The new method to gain the transfer function of the electric actuator is introduced, By this method, through analyzing each part of the electric actuator, open-loop transfer function is derived with voltage of power supply as the input and the feedback voltage as the output, With the solution of differential equation, a simple, fast method for determining the parameters of transfer function of actuator is proposed to get these parameters. It is proved by the experiment and Matlab emulation that the method is very simple and quick.
