Re: How Tune PID in octave using Frequency Response data

[shall689]

Hello Nicklas,

I have the open loop frequency response of 1/2 bridge inverter capacitor
current (using PSIM).  Now I would like to convert that response into a
transfer function so that I can create the closed loop response (as you
mentioned).

I do have an exact transfer equation for the capacitor voltage with respect
to duty cycle so maybe that can somehow be changed to capacitor current
since capacitor current equals C*dv/dt. Maybe just multiplying by Cs would
do it?
