自动控制系统稳定性教学中的思政元素设计

针对传统自动控制原理课程教学的不足,将某型号转子绕线机控制系统引入系统稳定性案例教学课堂。通过对案例的数学建模,分别应用时域分析法中的劳斯判据、赫尔维茨稳定判据,系统输出曲线和频域分析法中的奈奎斯特稳定判据及对数稳定判据分析控制系统的稳定性。课程将思政元素与系统稳定性知识有机融合,引申出“条条大路通罗马”的问题解决思想和引导学生认识社会系统稳定的重要意义及自身责任。

In view of the shortcomings of the traditional Automatic Control Principle course teaching,the control system of a certain type of rotor winding machine is introduced into the system stability case teaching class.Through the mathematical modeling of the case,the stability of the control system is analyzed by applying the Routh criterion,Herwitz stability criterion and system output curve in the time domain analysis method,and the Nyquist stability criterion and logarithmic stability criterion in the frequency domain analysis method.The course organically integrates ideological and political elements with knowledge of system stability,extends the problem-solving idea of"all roads lead to Rome",and guides students to understand the importance of social system stability and their own responsibilities.
