Hello
Getting the following error when tried linearzing power facotor model
In "frestimate(modelname,op,io,in)", it is required for each of the linearization input I/O points that the sample time of the Simulink signal where it is located is one of the following: 1. It is either continuous or fixed in minor time step. 2. Its sample rate is equal to the sample rate of the input signal "in". The linearization I/O io(1) does not satisfy this requirement. Consider either changing the sample time of Simulink signal where io(1) is located to continuous sample time or changing the sample time of input signal "in".
Input pertuberation : Duty Cycle
Open Loop Output : Inductor current
Any idea how to approach the problem ?

Hi, both input linearization point and output measurement point are required to be equally sampled and must match the perturbation signal's sample time. Please, check the sample time in your model by going to the Debug tab -> Information Overlays -> Colors in the section Sample Time.
If you there are different sample times, consider to either fix your model sample time(s) or using Rate Transition blocks to set the smple time(s) as appropriate.
Hope this helps!

I tried Antonio's model and unfortunately the simulation goes on forever and matlab will not respond to clicks (although it does not say it's not responding), it just says it's still simulating the model. I'm running a ryzen 5 3600 with 16GB DDR4 RAM. Is this normal?
