Keywords: speed estimation | first order estimator | second order estimator | rotor field oriented control | mathematical model | AC drives

Two structures of speed estimator for AC drive system are developed in thispaper. The mathematical models and the simulation results, via numerical simulation,are presented. The utility of the estimator is important for the speed control or for theadvanced control synthesis such as optimal vector control of induction motor drives.Besides of speed estimation objective, the proposed method increases the robustness ofestimators to measurement signal noises.
