add_block(​'powertrai​nlib/Power​train','Ge​nerator_to​_Electric_​Motor/Powe​rtrain’);

add_block('powertrainlib/Powertrain','Generator_to_Electric_Motor/Powertrain’);

Error due to multiple causes.

Caused by:

Unable to load block diagram 'powertrainlib'

There is no block named 'powertrainlib/Powertrain'

how to fix this?

The full path of the source block is incorrect. The best way to handle this, is to do it manually.

If you are able to open the powertrain library manully, then select the block you want to add, go to MATLAB Command Window, type 'gcb'. It will show you the correct path of the block. Then you can use it in the add_block(). For example:

>> gcb

ans =

'autolibmotorctrlr/Interior PM Controller'
