摘　　要：传递函数是控制理论中对系统进行分析、综合的基本数学工具。该文设计的实验综合了控制工程基础课程中关于系统、传递函数和一阶系统的时间响应的内容，并结合计算机仿真软件Matlab，对直流电动机系统的传递函数进行了实验测定和仿真研究，可以更加有助于对课程内容的理解和基本方法的应用。Transfer function is a basic mathematical tool for analyzing and synthesizing control system. A comprehen- sive experiment was designed to determine transfer function for DC motor. A number of contents in control engineering have been applied in this experiment, including in system, transfer function and time response of an order system. The software Matlab was used to deal with experimental result. Based on experiment and simulation analysis, it was not difficult to understand and use the transfer function for direct current electromotor for students. It is a benefit way to improve the teaching method.
