Abstract

método e um dispositivo para produzir um sinal de ponto de ajuste. o sinal de ponto de ajuste (c1) reapresenta uma vazão de combustível que a unidade de dosagem (2) tendo uma válvula deslizante deve fornecer ao sistema de injeção de combustível (4) de uma câmara de combustão em um motor de turbina, a posição da válvula (2a) dependendo do sinal de ponto de ajuste. o método compreende: obter um primeiro sinal (s1) que representa uma medição como fornecida por um fluxímetro (6) de uma vazão de combustível injetada na câmara; avaliar um segundo sinal (s2) que representa a vazão de combustível injetada na câmara com base em uma medição (m) da posição da válvula; estimar um terceiro sinal (s3) representativo da medição fornecido pelo fluxímetro por aplicação de um modelo digital do fluxímetro ao segundo sinal; e produzir o sinal de ponto de ajuste de um sinal de compensação ao primeiro sinal, o sinal de compensação sendo obtido por subtração do terceiro sinal a partir do segundo sinal.
