The decibel calculation for mag is computed as 20log 10, where is the system's frequency response.
The magnitude is plotted in decibels (dB), and the phase in degrees. Bode diagram design is an interactive graphical method of modifying a compensator to achieve a specific open-loop response (loop shaping). When invoked without left-side arguments, bode produces a Bode plot on the screen.
To change between Hertz (Hz) and radians per second (rad/s) on the bode plot, use the following commands: s. bode computes the magnitude and phase of the frequency response of LTI models. Legend is displayed in the second plot (Phase plot) Changing the Frequency Units on the Bode Plots. When I return to the first figure, with figure(1), and try figure(1) text(10,-20,'text') Something like the figure pointer always returns to the second plot (phase graph).

When I want to reach the plot in order to put a legend with text(), for instance, is easy to reach the second plot. If I want to overlap two or more systems frequency responses, I use bode(sys1,sys2.)
#Bode matlab how to#
I know how to create the Bode plots with bode() function. En la presente practica se busca analizar la respuesta en frecuencia de distintas funciones utilizando el software MATLAB como herramienta para el estudio de los diagramas de bode de dichas funciones, para esto es necesario utilizar la funcin 'Bode' de MATLAB.
