Abstract

"MéTODO PARA CONTROLE DE COMANDOSELETROMAGNéTICOS PARA COMANDAR AS VáLVULAS DEADMISSãO E EXAUSTãO DE MOTORES DE COMBUSTãOINTERNA". Para um atuador eletromagnético (1,25) acoplado auma respectiva válvula (2,26) e provido com um membro móvelferromagnético (3, 27) conectado com ao menos um ponto daválvula, um par de eletromagnetos (6, 29) dispostos em ladosopostos com respeito com ao membro móvel ferromagnético (3, 27)e um membro elástico (7, 30) adaptado para manter a válvula emuma posição de descanso. O método compreende os estágios dedetectar a posição atual (Z) e a velocidade atual (V) da válvula (2,26), determinando a posição de referência (Z~ R~) e a velocidadede referência (V~ R~) da válvula (2, 26) e minimizando diferençasentre a posição de referência (Z~ R~) e a posição atual (Z) e entrea velocidade de referência (V~ R~) e a velocidade atual (V) daválvula (2, 26) por meio de um controle de ação de retorno.
