摘要
在控制系统的时域分析中,许多高阶系统均可近似当做二阶系统进行分析和设计,故二阶系统的性能分析显得十分重要。MATLAB LTI Viewer 工具箱是线性时不变系统观测器工具箱,使用它对控制系统进行分析,具有直观、准确的特点。本文采用MATLAB LTI Viewer 工具箱对二阶系统阶跃响应进行分析,对照不同阻尼比下二阶系统阶跃响应曲线,了解各性能指标参数变化对系统性能的影响。
In the time domain analysis of control systems,many high-order systems can be approximated as second-order systems for analysis and design,so the performance analysis of second-order systems is very important.The MATLAB LTI Viewer toolbox is a linear time-invariant system observer toolbox,which is intuitive and accurate to analyze the control system.In this paper,the MATLAB LTI Viewer toolbox is used to analyze the step response of the second-order system,and the step response curves of the second-order system under different damping ratios are compared to understand the influence of various performance index parameters on the system performance.
