So I know this is probably a simple problem, or not even a problem at all, and as you can probably see I'm still starting to get familiar with these concepts, however, in my head this is not making sense. My problem is that after I configure my buck-boost converter probably to give me 30V from a 12V source properly on a 15 ohm load, I attach my motor armature circuit and that voltage starts acting weird on the output load, and at the armature resistor. I've also tried using a non-inverting buck-boost, but it gives me even less voltage current which is even harder to solve. I've alternatively tried to invert the voltage at the armature but to no avail, by inverting the terminals, which doesn't make sense since the current that goes through is positive. I am going to put pictures of what I'm describing under this:

This is the picture of the output of the converter (without simple motor armature attached) at 0.7 duty cycle.

This snapshot shows my specific error. V-out voltage shape makes a little sense in my head since it behaves like a third order system (I believe) and is fine I guess. The problem is I am not getting close to my boosted voltage, and it is still negative which will spin the motor the opposite way. This project is just me trying to see how I would design a simple working motor arm, I already mechanically designed it but I am still working on the electronic and control.

This is another snapshot of the non-inverting buck-boost. At this point I've tried everything and I'm starting to thing it might be a complete ideological or design flaw from my end.
