A robust observer for switched-reluctance motors
Résumé
We present a simple state observer for switched reluctance motors using stator currents. The estimation error dynamics is showed to be input-to-state stable with respect to (current, velocity and angular position) tracking errors as well as relative to load-torque compensation mismatch. The state estimator is designed in the context of the certainty-equivalence principle and proportional-integral-derivative control.
