Оперативное определение активного сопротивления статора и электромагнитной постоянной времени ротора асинхронной машины

Abstract

Synthesized algorithm for the active resistance stator and rotor time constant induction motor with a fixed rotor. The basis of the observer laid the mathematical model of asynchronous motor in stationary coordinate system. The algorithm is based on the phased application of recursive least squares method which guarantees high accuracy of the parameter estimates for the minimum time. To use the identifier to have information on the inductance of stator, rotor and mutual inductance. Simulation results show the effectiveness of the proposed method of identification.
