Frequency Plot(or bode plot) in SIMULINK

[samiurrehman]

Dear all,

Can anyone describe as to how we can plot frequency response in SIMULINK-MATLAB. One way is to use spectrum analyzer but it does not give accurate results for continuous time systems...another way could off course be to use commands but I need something which can compute bode plots itself when the system output is given to it as input.

Thanks

Hello,

You can try with linearization.
1-right-click on the input line->linearization point->input
2-right-click on the output line->linearization point-> output
3- go on tools->control design->linear analysis
4- At the bottom select the output you are interested in
5- click on linearize and you get the bode plot
