Abstract

um método (100) para se estimar uma velocidade de um motor de indução que inclui aplicar (102) uma tensão ao motor de indução e medir (104) uma corrente do motor de indução. uma transformação rápida de fourier de corrente (fft) da corrente é, então, determinada (106) e um deslizamento do motor de indução é calculado (108) com base na corrente fft. uma velocidade do motor de indução é, então, (110) estimada, com base no deslizamento do motor de indução.
