Immersion Based Observer for the Switched Reluctance Motor

Résumé

This article presents a high-gain Kalman-like observer forthe switched reluctance motor that can reconstruct theangular position and velocity from the measured variables,i. e., stator currents and voltages. This is possible afterthe results obtained from an observability analysis, which in turn permits the application of an immersion to transform the motor model into a suitable form for the observer implementation. Numerical simulations are incorporated to explain and validate the observer design. The procedure includes an active phase detection stage anda current-based speed controller that defines the commutation required for this kind of motors. The proposed observer is capable of reconstructing the mechanicalvariables (rotor position and speed) by employing only electrical ones (currents and voltages).
