Speed ​​loop, current loop ADRC principle

1. The ADRC of the speed loop


ADRC can refer to other literature for specific articles. Anyway, the ADRC of the speed loop includes TD (tracking differentiator), NLSEF (non-linear error feedback rate), and ESO (extended state observer).
2. Current loop ADRC

Summarize

The overall feeling is good, but I still hope that interested students can work with me to improve and innovate ADRC. If you need a model, please consciously follow me, hey, like it! !
