Abstract
UN PROCEDIMIENTO PARA RECONOCER E IDENTIFICAR FALLOS EN SENSORES PARA MEDIDAS DE ESTADO, QUE SON LIGADOS CON MEDIDAS DADAS DIRECTAMENTE POR LOS SENSORES, MEDIANTE UNA ECUACION DE MEDICION M = HX + W, SIENDO M UN VECTOR DE LAS MEDIDAS DE MEDICION, X UN VECTOR DE LAS MEDIDAS DE ESTADO Y H LA MATRIZ DE MEDICION, Y DONDE EL ORDEN DE M ES MAYOR QUE EL ORDEN DE X, TIENE LOS PASOS DE PROCESAMIENTO: (A) DEFINICION DE VECTORES DE VALIDACION VI COMO VECTORES DE COLUMNAS DE UNA MATRIZ P = [V1 V2...VN] (B) DETERMINACION DE UN VECTOR DE PARIDAD V COMO ELEMENTO DE UN ESPACIO DE PARIDAD, QUE ES EL COMPLEMENTO ORTOGONAL DEL ESPACIO DE SEÑAL, COMO COMBINACION LINEAL DE LOS VECTORES DE VALIDACION CON LOS CORRESPONDIENTES ELEMENTOS MI DEL VECTOR DE MEDICION M: V = .... (C) FORMACION DE UNA FUNCION DE DETECCION DF = < V V > COMO PRODUCTO DE ESCALA DEL VECTOR DE PARIDAD CONSIGO MISMO, Y COMPROBACION, SI ESTA FUNCION DE DETECCION ES MAYOR O MENOR QUE UN VALOR LIMITE PREVIAMENTE DADO. SOBREPASAR ESTE VALOR LIMITESEÑALIZA LA EXISTENCIA DE UN FALLO. (D) AL EXISTIR UN FALLO, SE PUEDEN HACER CALCULOS DE FUNCIONES DE LOCALIZACION DE LOS COMPONENTES DEL VECTOR DE PARIDAD Y HACER LA DETERMINACION DE LA FUNCION DE LOCALIZACION MAXIMA DE LA CUAL SE PUEDE DEDUCIR EL SENSOR QUE FALLA. (E) RECONFIGURACION DE LAS SEÑALES DE SENSOR, TENDIENDO EN CUENTA DE ESTADO DE FALLO CALCULADO DE ESTA MANERA
