摘　　要：针对“自动控制原理”课程中应用阻抗法求解电路系统传递函数的内容,进行了教学探讨。首先,总结了求解传递函数的主要方法。然后,重点讨论了阻抗法的数学本质,通过严格的数学分析,得出电路系统的阻抗Z(jω)与其传递函数G(s)的关系:G(jω)=Z(jω)。最后,给出教学中若干采用阻抗法获取无源、有源网络传递函数的案例,体现了该方法的简便性和有效性。讨论的内容对完善传递函数教学有着积极意义。Aiming at the content of impedance method to solve the transfer function of circuit system in the course of Automatic Control Principle,the teaching is discussed.Firstly,the main methods of solving transfer function are summarized.Then,the mathematical nature of impedance method is discussed.Through rigorous mathematical analysis,the relationship between the impedance Z(jω) and the transfer function G(s) of the circuit system is obtained:G(jω)=Z(jω).Finally,some passive networks and active networks in the teaching process are given to obtain the transfer function as calculation cases,which shows the simplicity and effectiveness of this method.The content discussed is of positive significance to improve the teaching of transfer function.
