Abstract

CUANDO SE PROCESAN LAS SEÑALES DE POSICION DE SISTEMAS DE CAPTACION (G1, G2), EN PARTICULAR DE CODIFICADORES ANGULARES ABSOLUTOS A INTERVALOS DE TIEMPO PREFIJADOS (DELTA T), ERRORES DE MEDICION ESPORADICOS PUEDEN PERTURBAR EL FUNCIONAMIENTO. POR TANTO, DE ACUERDO CON LA INVENCION A CADA MEDICION DE POSICION SIGUE INMEDIATAMENTE OTRA MEDICION AUXILIAR (DELTA T). ESTA MEDICION SE UTILIZA ENTONCES COMO LA MEDICION DE POSICION, CUANDO RESULTA QUE LA VERDADERA MEDICION DE POSICION DEMUESTRA ESTAR AFECTADA DE ERROR, PUES PARA LA MEDICION PRECEDENTE EXISTE UNA DIFERENCIA DE VELOCIDAD, QUE NO SE ESPERABA A CAUSA DE LA ACELERACION DE FUNCIONAMIENTO.
