Needs to be adapted if Ld and Lq are available in the future. ⚠️ What if users have set phase resistance and phase inductance but were using default PI parameters ? Is there an impact ? ### if phase resistance and phase inductance are not known: Same SimpleFOC default values as before are used. ### Users that have already tuned their PIs: They will overwrite Kp and Ki from their code.
