A new identification procedure to identify unknown parameters of induction motors for self-commissioning of vector controlled electrical drives is developed, substantiated and experimentally verified. Our algorithm uses a full-order adaptive observer to estimate stator fluxes and motor parameters: rotor resistance, stator (rotor) inductances, and, magnetizing inductance. Experiments demonstrate that...
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...
A new identification procedure to identify unknown parameters of induction motors for self-commissioning of vector controlled electrical drives is developed, substantiated and experimentally verified. Our algorithm uses a full-order adaptive observer to estimate stator fluxes and currents and motor parameters: rotor resistance, stator (rotor) inductances, and, magnetizing inductance.

This paper proposes an online method for the estimation of the stator resistance and the permanent-magnet (PM) flux in sensorless PM synchronous motor drives. An adaptive observer augmented with a high-frequency signal injection technique is used for sensorless control. The observer contains excess information that is not used for the speed and position estimation. This information is used for the...
