SUMMARY

This discussion focuses on combining two Bode plots in MATLAB using the 'hold on' command. Users are instructed to first plot one Bode plot, then utilize 'hold on' to overlay the second Bode plot on the same figure. The importance of using 'hold off' after completing the plots is emphasized to prevent further additions to the figure. This method allows for effective comparison of frequency response characteristics in control systems.

PREREQUISITES
  • Familiarity with MATLAB plotting functions
  • Understanding of Bode plots and their significance in control systems
  • Basic knowledge of MATLAB commands such as 'hold on' and 'hold off'
  • Experience with frequency response analysis
NEXT STEPS
  • Explore MATLAB's 'bode' function for generating Bode plots
  • Learn about customizing plot aesthetics in MATLAB
  • Investigate the use of 'subplot' for multiple plots in a single figure
  • Study the implications of Bode plot analysis in control system design
USEFUL FOR

Control system engineers, MATLAB users, and anyone interested in visualizing frequency response data effectively.

Im trying to plot two bode plots on one graph. Can anyone help?

Plot one of the bode plots. Then type

Code: 
hold on

to instruct any further plots to draw in the same figure. Finally, plot your other Bode plot.

thank you!
 
Don't forget to turn hold off.
