Abstract

método e sistema para estimar ângulo do rotor de uma máquina elétrica amostras de posição são armazenadas a partir de um codificador acoplado em uma máquina elétrica com ímã permanente. um processador de dados determina primeiras mudanças na posição entre sucessivas amostras de posição e segundas mudanças entre sucessivas primeiras mudanças na posição. um processador de dados determina se cada primeira mudança na posição é, no geral, crescente, decrescente ou constante. um fator de movimento corretivo é aplicado em cada amostra de posição armazenada com base na condição de a primeira mudança na posição ser, no geral, crescente ou decrescente. o processador de dados estima um ângulo final do rotor da máquina elétrica com base em uma amostra de posição em particular das amostras de posição e em uma correspondente primeira mudança na posição associada com a amostra de posição em particular das amostras de posição correspondente a um respectivo tempo.
