Bode Plot将系统的频率特性 G(jω) 用图示的方法表示出来。Bode Plot一大优点就是把整个频率特性的作图分解为传递函数的不同零极点和增益的幅频和相频曲线的简单叠加。我们知道一个传递函数中的零极点和增益决定了系统的响应形式,因此通过研究每个零极点和增益的幅相曲线,就可以理解每个环节在整体系统中作用。最后通...
What are bode plots? From the series: Understanding Bode Plots Learn the principal characteristics of a Bode plot in this MATLAB® Tech Talk by Carlos Osorio. This video explains how a Bode plot describes the frequency response of a linear time-invariant system and the plot’s primary chara...
The Bode plot is a popular tool with control system engineers because it lets them achieve desired closed loop system performance by graphically shaping the open loop frequency response using clear and easy-to-understand rules. In addition, engineers can easily see the gain margin and phase margin...
