Synthesis and Investigation of Algorithm for Estimation of Active Stator Resistance of Asynchronous Motor with Fixed Rotor
The paper proposes an algorithm for online identification of active stator resistance. Algorithm synthesis has been developed on the basis of a recursive least squares method. The problem has been solved for induction motor model defined in the stationary stator frame α–β-coordinating system. An ana...

| description | The paper proposes an algorithm for online identification of active stator resistance. Algorithm synthesis has been developed on the basis of a recursive least squares method. The problem has been solved for induction motor model defined in the stationary stator frame α–β-coordinating system. An analysis of negative factors deteriorating the identifier operation has been made in the paper. The analysis has revealed the following: measured signals are noisy due to quantization and differentiation; dynamic model of an induction motor provides only approximate presentation about actual processes in the electromagnetic system of the machine. The paper presents results of a system simulation while applying the proposed algorithm that confirm the fact that the estimated value of the active stator resistance tends to a true value with high accuracy. The identification test assumes a fixed rotor and nominal parameters uncertainty, but the flexible structure of the algorithm allows to use it as for single-phase excitation so for full-phase control of the induction motor with freely rotating motor. |
