I'm a relatively novice user of matlab.

I'm currently trying to run this model/simulation that is for a regenaritve braking model. I've hit this snag where the decoder in the model says "DriveInternalModel" not found. I've been trying to figure out or not if this library needs to be installed, if the model is incorrect, or if it's something else. This is the error code.

Error:Failed to load library 'AC7DriveInternalModels' referenced by 'BLDC_Battery_2018/Controller/Decoder'.

This is also the image of the source block.

Here is a link to the model from the file sharing site: https://www.mathworks.com/matlabcentral/fileexchange/90411-bidirectional-vsi-based-regenerative-braking-for-bldc-motor

Any help or a point in the right direction would be greatly appreciated!

Hi Saul,

The library was available until R2024b, as mentioned in the captured release note below..

https://www-test1.mathworks.com/help/sps/release-notes.html?s_tid=doc_srchtitle&searchHighlight=AC2+motor+drive#:~:text=Motor%20drive%20examples%20and%20the%20example%20library%20that%20supports%20them%20have%20been%20removed

Best regards,

Song-Hyun

Thank you. I installed an older version of matlab (the R2018a version) which was the one that was used to make the model, and everything was working. Based on yours and Leepakshi's answer, the library was indeed removed. Thank you all for the help!

Hi Saul,

I tried running it on the latest versions—R2024b, R2025a, and R2025b—but I am still getting the same error. It must have been removed from later versions.

If needed, you can connect with MathWorks Support using the following link: https://www.mathworks.com/support/contact_us.html

Hope this helps!

Thanks
