Abstract

This work describes a method for estimating all electrical parameters of an induction cage motor using a continuous time model and a standard recursive least square algorithm. The problem of derivative calculation of voltage and currents signals, inherent to continuous time models, is solved by polynomial interpolation. This simple yet effective methodology is applied to known speed operation, when the transient response of the motor excited by a PWM inverter is used during the estimation. Experimental results are included and confirm the good performance of the proposed procedure
