基于Matlab的直流电机型位置随动系统分析
|
摘要
针对时代发展和人才培养方案对电气控制类大学生的具体要求,探索了《自动控制原理》教学内容改革的新途径。引入了直流电机型位置随动系统,讨论了系统结构和组成,建立了系统的数学模型。运用Matlab绘制了系统的阶跃响应曲线和系统的Bode图,并判断闭环系统是不稳定的。用串联超前滞后的校正方法对系统进行了校正,绘出了校正后的系统阶跃响应曲线和Bode图,并判断出校正后的系统是稳定的。
Aiming at the specific requirements of the development of the era and the personnel training program for college students of electric control,the new approach for the reforming the teaching content of The Automatic Control Principle is explored. The DC motor position accompanying system is introduced. The structure and working principle are illustrated. The mathematical model of the system is established. Using Matlab the system step response curve and Bode figure are drawn. It shows that the closed-loop system is unstable. The calibration method of series lead lag is used to correct the system. The step response curve and Bode diagram of the corrected system show the stability of the corrected system.
