Abstract

ESTE METODO INCLUYE LOS PASOS DE GENERACION DE UNA SEÑAL DE ACELERACION (S) RELACIONADO CON LA INTENSIDAD DE LA VIBRACION EN UN MOTOR; COMPARACION DE LA AMPLITUD DE LA SEÑAL DE ACELERACION (S) CON UN VALOR DE AMPLITUD DE REFERENCIA PREDETERMINADO (S{SUB,TH}); GENERACION DE UNA SEÑAL DE ERROR CUANDO LA AMPLITUD DE LA SEÑAL DE ACELERACION (S) SUPERA UN VALOR DE AMPLITUD DE REFERENCIA PREDETERMINADO (S{SUB,TH}); DETERMINACION DE UN VALOR DEL ANGULO DE ARRASTRE DE CRUCE (A{SUB,O}) CUANDO LA AMPLITUD DE LA SEÑAL DE ACELERACION (S) SUPERA UN VALOR DE AMPLITUD DE REFERENCIA PREDETERMINADO (A{SUB,TH); Y GENERACION DE UNA SEÑAL DE ERROR EN EL CASO DE QUE EL VALOR DEL ANGULO DE ARRASTRE DE CRUCE (A{SUB,O}) ES MENOR QUE EL VALOR DEL ANGULO DE REFERENCIA PREDETERMINADO (A{SUB,TH}).
