It is also available for Linux, Mac and Windows.Īssuming you have Octave installed on your machine, you will need to download and install the 'control' package. GNU Octave is a free and open source Science and Mathematics programming language the is nearly a drop-in replacement for MATLAB in terms of syntax (though you may run into some minor differences depending on the application). Now when you mouse over the plots you will see updated values for magnitude and frequency as you move the pointer along the curve. Under the 'Cell' tab select 'Probe Info' then check the box for 'nearest point on line'. To get accurate data along the curve simply click on the magnitude or phase plot, head over to the vertical menu on the right side of the screen. The range of values on the frequency axis can be adjusted as well. Many different formatting arguments can be passed to the 'BodePlot' function in terms of line styles, colors, as well as the number of points to be plotted. Scrolling down slightly displays the magnitude and phase plots: sys := TransferFunction(1.6/(s*(s^2+s+16))) īy hitting 'Enter' after each command you end up with the following output:.We will proceed to construct the Bode plots for the following transfer function:

It is compatible with Linux, Mac and Windows. Maple is a well known proprietary mathematics software package available for purchase. We will use the same transfer function as a means of demonstrating the construction of Bode plots with both programs. While there are multiple software packages that can accomplish this task, we will specifically look at Maple and GNU Octave. The fastest and easiest way to construct an accurate Bode plot is via software. Bode plots (software) Constructing Bode plots with Maple and GNU Octave
