A method for evaluating the sensitivity of speed estimation to parameter variations in inverter motor drives with microprocessor based control is proposed in the paper. By using a full order flux: asymptotic observer, the step by step analytical determination of the stator current error is carried out. In this way, the motor speed can be expressed as a function of motor parameters, allowing sensitivities evaluation.

Abstract
A method for evaluating the sensitivity of speed estimation to parameter variations in inverter motor drives with microprocessor based control is proposed in the paper. By using a full order flux: asymptotic observer, the step by step analytical determination of the stator current error is carried out. In this way, the motor speed can be expressed as a function of motor parameters, allowing sensitivities evaluation.File in questo prodotto:
