摘要
应用MATLAB软件,对已有的控制系统模型求解,并研究和分析其性能。着重说明如何利用MATLAB控制系统工具箱中的函数tf和feedback来求解典型线性反馈控制系统的开环和闭环传递函数,绘出相应的阶跃响应曲线。并利用Simulink仿真软件对其进行分析。
This paper used MATLAB software to solve the problem existing in the common control system model ,and researched its performance. It focused on how to use function ＇tf＇ and ＇feedback＇ in MATLAB toolbox to solve typical linear feedback control system for open-loop and closed-loop transfer function, and drew the corresponding step-response curves. Finally the paper used Simulink simulation software to analyze the system.
