bodeplot
LaTeX package to plot Bode, Nichols, and Nyquist diagrams. Inspired by the bodegraph
package.

Limitations
1 Before version 1.2, in pgf
mode, the package set trig format plots
to rad
globally. Version 1.2 onwards, this option is passed to each addplot
command individually so it does not affect non-bodeplot
plots. To roll back to pre-v1.2 behavior, load the package with \usepackage[pgf]{bodeplot}[=2024-02-06]
.
- TF commands are wrapped between -180 and 180 degrees in
pgf
mode. - Version 1.0.8 and newer store
gnuplot
temporary files in the working directory. Use class optiondeclutter
to restore pre-v1.0.8 behavior. Optiondeclutter
can cause errors if used with atikzexternalize
prefix.
Compilation instructions
1) latex bodeplot.ins
to generate bodeplot.sty
2) To compile documentation (needs gnuplot
on system PATH):
pdflatex bodeplot.dtx --shell-escape makeindex -s gind.ist bodeplot.idx makeindex -s gglo.ist -o bodeplot.gls bodeplot.glo pdflatex bodeplot.dtx --shell-escape pdflatex bodeplot.dtx --shell-escape
Added functionality over bodegraph
- New
\BodeZPK
and\BodeTF
commands to generate Bode plots of any transfer function given either poles, zeros, gain, and delay, or numerator and denominator coefficients and delay - All plots are fully customizable using
pgf
options (see package documentation for a full list of commands, environments, and options) - Support for unstable poles and zeros.
- Support for complex poles and zeros.
- Support for general stable and unstable second order transfer functions.
- Support for both
gnuplot
(default) andpgfplots
(package optionpgf
). - Support for
rad/s
(default) andHz
(package optionHz
orpgf
keyfrequency unit=Hz
for per-plot change) frequency units. - Support for
deg
(default) andrad
(package optionrad
orpgf
keyphase unit=rad
for per-plot change) phase units. - Support for linear and asymptotic approximation of magnitude and phase plots of any transfer function given poles, zeros, and gain.
Basic Bode/Nyquist/Nichols commands
See package documentation for a full list of commands, environments, and options.
- Given Zeros, Poles, Gain, and Delay (asymptotic and linear approximation available for systems without delay):
BodeZPK % (OR NicholsZPKsamples=1000 OR NyquistZPKsamples=1000) {% z/{0,{-0.1,-0.5},{-0.1,0.5}}, % zeros at s = 0, s = -0.1 - 0.5j, and s = -0.1 + 0.5j p/{{-0.5,-10},{-0.5,10}}, % poles at s = -0.5 - 10j, and s = -0.5 + 10j k/10, % gain d/0.01, % delay } {0.01} % frequency range start {100} % frequency range end- Given Numerator and denominator coefficients and delay (does not support approximation):
BodeTF % (OR NicholsTFsamples=1000 OR NyquistTFsamples=1000) {% num/{10,2,2.6,0}, % numerator coefficients den/{1,1,100.25}, % denominator coefficients d/0.01, % delay } {0.001} % frequency range start {100} % frequency range end

bodeplot – Draw Bode, Nyquist and Nichols plots with gnuplot or pgfplots
This is a LaTeX package to plot Bode, Nichols, and Nyquist diagrams. It provides added functionality over the similar bodegraph package:
- New \BodeZPK and \BodeTF commands to generate Bode plots of any transfer function given either poles, zeros, gain, and delay, or numerator and denominator coefficients and delay
- Support for unstable poles and zeros.
- Support for complex poles and zeros.
- Support for general stable and unstable second order transfer functions.
- Support for both Gnuplot (default) and pgfplots (package option pgf).
- Support for linear and asymptotic approximation of magnitude and phase plots of any transfer function given poles, zeros, and gain.
