Control System Design methods using Octave.

I mainly work with PSIM. 

PSIM has a general control system design software named smartctrl.  Matlab
has something simlar, I think.

According to https://www.youtube.com/watch?v=tpoCpC-oX7Q, the following
steps in smartctrl can be taken to determine the design parameters for a
specific control system:
1. import the bode plot obtained from an AC sweep of your simulation into
smartctrl.
2. Select a sensor (voltage divider and ect) from the smartctrl.
3. Select a controller (PI or etc).
4. Afterwards, select a point from the cross over frequency vs Phase Margin
solution map that gives a specific step response.  Smartctl also shows the
bode plots for the closed loop response.

Smartctrl gives the P and I for the specific point picked in the solution
map.

Is there anyway to get octave to give the same type of information.   

Thanks,
Stephen
