摘要：

A novel sensorless speed identifier for real-time application in induction motor drives under steady-state and transient conditions is proposed. It is based on the calculation of rotor slot harmonic (RSH) frequencies using ail adaptive digital filter. ft outperform other analog or spectrum-based RH speed identifiers in terms of accuracy and speed of response, The new identifier measures the speed with less than 0.1% error bs processing the stator current on a sample-by-sample basis, It is also capable of tracking; speed transients of high slew rates with high accuracy. The authors believe this to be the first effective tracking of RSH's during transients ever reported. The proposed algorithm is computationally very efficient and requires only a single processor for its real-time implementation, Simulated and experimental data were used to validate the algorithm.
