- Open-loop analysis with stand-alone boost converter - use an ideal voltage source with value an average of PV voltage and a resistor as output with value R = V*V/P, where V is the expected voltage your motor should work at and P is the rated power
- Tweaking parameters - the boost converter is notorious to be challenging to control in pure voltage mode since the designer must reduce the destabilizing effect of the half-plane zero. You can follow this design procedure.
- Control design - did you know that you can design your controller directly on the switch-mode converter? This is made possible thanks to a systematic procedure based on Frequency Response Estimation and tools that leverage on the classic control theory available with Simulink Control Design. If you need more info, I advice you to look into this training course: Power Electronics Control Design with Simulink and Simscape.
- Once the voltage-mode-controlled boost converter is fully tested as standalone, you may replace the ideal voltage source with your PV panel model and the resistive load with your motor.
Simscape "Boost Converter" not functioning as expected.

I am currently trying to utilize a Simscape Boost Converter block to step-up incoming voltage from PV modules having about 7.2V to 16.8V to powerup BLDC motors as shown in the attached picture.
However, whatever I try with various parameter values for the "Boost Converter" block and "DC-DC Voltage Controller" block, both incoming voltage and the outgoing voltage are same to be around 7.2V. I wonder what I am doing wrong in here.
