Abstract

This paper presents linear estimation techniques used to identify the stator resistance, the stator leakage inductance (transient inductance), the stator self inductance and rotor time constant of an induction motor without measuring its speed. Such estimation is important to achieve high performance for sensorless field-oriented control of induction motor drives. The discrete-time parameter estimation models express the relationships of the dynamic machine model in terms of measurable stator voltages, currents and an estimated motor speed. These models are represented by linear regression equations from which machine parameter vectors can be obtained using a recursive least squares (RLS) estimation algorithm. Moreover, a robust speed estimator based on a model-reference adaptive system (MRAS) is proposed to use the estimated parameters for accurate estimation of motor speed. The estimated motor speed is used iteratively in the parameters linear estimation models and is fed back in a sensorless field-oriented control of motor drive. The accuracy of parameter estimation is good regardless of load conditions. Simulation results validate the proposed scheme with reasonable accuracy of the estimated parameters as well as excellent performance of the motor drive.
