Bode plot with variable pulse generator

i try to get bode plot with introduce perturbation in frequency of variable pulse generator but i cant get the bode plot also not getting any error but if i give perturbation in any other parameter like the voltage it was giving the bode plot please help me to get bode with frequency variation.

Hi Ponnanthiraja,

My understanding is that you are attempting to obtain a Bode plot by perturbing the frequency parameter of a Variable Pulse Generator.

Whereas frequency response estimation generally requires perturbations on continuous system inputs rather than on pulse-generator timing parameters.

I would suggest you to try the below approaches and see if this helps to solve your issue.

Apply the perturbation to a continuous input signal (such as voltage, current, duty cycle, or control input) instead of the pulse generator frequency.

Verify whether the Variable Pulse Generator frequency is supported as a linearization or frequency-response analysis input.

If the goal is to analyze how the system responds to frequency variations, consider replacing the pulse source with a sinusoidal test signal or using Simulink Control Design/Frequency Response Estimator input points that support frequency-response analysis.

Hope this helps!
