摘　　要：随着经济的不断发展,现代工业技术也随之不断提升,自动控制系统在各个领域得到了广泛应用.然而,系统的稳定性是保证工业过程正常运行的关键因素之一.因此,对自动控制系统的稳定性进行分析和评估显得尤为重要.判定自动控制系统稳定性的方法有很多,但是,过程通常非常繁琐,结果也不准确性.采用MATLAB软件仿真对系统的特征根进行计算,通过观察零极点分布和绘制根轨迹,能够更快、更准确地分析其稳定性.With the continuous development of the economy,modern industrial technology has also been upgraded,and automatic control systems have been widely used in various fields.However,the stability of the system is one of the key factors to ensure the normal operation of industrial processes.Therefore,it is particularly important to analyze and evaluate the stability of automatic control systems.There are many ways to determine the stability of automatic control systems,and although the stability and performance can be analyzed by usual analysis methods,it is very cumbersome and inaccurate.Combined with MATLAB software simulation to calculate the characteristic root of the system,by observing the distribution of zero poles and plotting the root trajectory,its stability can be analyzed faster and more accurately.
