TMS320F280049: SFRA GUI gives incorrect cross over frequency

Sheldon He

Hi expert,

I am not sure what does Folg_cf means here, but it seems not the real cross over frequency and the stability margin here is also incorrect.

Thanks

Sheldon

Sheldon,

the Open Loop Gain Cross over frequency is based on the OL plot, you need to look at the OL plot not the plant.

You have plant selected in the drop box on the left. You need to select Open Loop Plot
