Abstract

UN METODO PARA CONTROLAR LA TEMPERATURA, POR EJEMPLO EN UN INYECTOR DE UN SISTEMA DE INYECCION DE TERMOPLASTICOS, QUE USA UN SISTEMA DE SERVOCONTROL EN CICLO CERRADO, EN EL QUE LA RESISTENCIA (R) DE CALENTAMIENTO ELECTRICO SE DESACTIVA PERIODICAMENTE DURANTE CORTOS PERIODOS DE TIEMPO (VC, VR), PARA EXTRAPOLAR LA TEMPERATURA REAL (TPL) DE LOS PLASTICOS (P) EN EL INYECTOR, Y CONTROLARLA CON TANTA PRECISION COMO SE PUEDA, Y RESTABLECER LOS PARAMETROS DEL SISTEMA DE SERVOCONTROL EN CICLO CERRADO.
