You can use these options to customize the Bode plot appearance using the command line. Use "tfdata", "getpvec", "getcov" for parameters and their uncertainties.Įstimated using TFEST on frequency response data "sysfr". plotoptions bodeoptions returns a default set of plot options for use with the bodeplot (Control System Toolbox) command. The normal relationship of axes to figure is just not quite present. This can lead to odd behavior when attempting to create multi-line titles, reformat line widths or font sizes, etc. The example from the doc is: > sys tf (1, 1 1) > h bodeplot (sys) > p getoptions (h) > p.FreqUnits 'Hz' > setoptions (h,p) Share Improve this answer Follow answered at 3:02 Phil Goddard 10. The bode command appears to use a normal semilogx plot and then apply patches ro something similar to the figure. 1 1 1 Add a comment 1 Answer Sorted by: 0 Yes, see the doc for bodeplot, and/or setoptions. bode automatically determines frequencies to. For the Bode plot below, I am trying to remove the title and the input/output line: I have found methods to null the title line, but these do not collapse it - which would make it pointless as my reason for removing the title is conserving the space it takes. The main issue with the bode command is reformatting of the plot. The plot displays the magnitude (in dB) and phase (in degrees) of the system response as a function of frequency. but the manual plot of the bode charts match the matlab bode() command for the charts, so I would say yes as far as the process goes. Hello, I have been trying to replicate a bode gain plot from a given. > mag = db(mag) % to get the magnitude in 20log dB Learn more about bode plot, control, theory Control System Toolbox. To change between Hertz (Hz) and radians per second (rad/s) on the bode plot, use the following commands: s. Assuming LTI_SYS is SISO then the commands below will convert mag and phase into the vectors you would expect Changing the Frequency Units on the Bode Plots. The mag and phase variables must come out as 3D arrays.
