Regenerative Braking using BLDC Motor

hi am developing a regenrative simple circuit using the vedio series and the model from how to design motor controllers using simscape electrical. i have made some changes to The back model and i am able to reach a point where i am able to chagre a capacitor bank at constant angular velocity source. Futher i wanted to integrate a brake controll with pid contoller whcih i am not able to figure out and want help with to complelete my regenrative model with respect to electrical side not consisdering the vehicle parameter right now.

If there are model or block which will be helpfull please pin the link. open to any sugessition and help.

thanks and regards

Hi @Shreyas,

Here are some useful documentation links for designing braking circuit using BLDC motor:

You can also refer to this MATLAB answer thread which has a discussion for this approach:
