Abstract
Una unidad de ensayo de diagnostico, una válvula de control y un método para medir determinísticamente uno o más parámetros, como ser banda muerta, tiempomuerto, tiempo de respuesta, ganancia o sobreactuacion, de un dispositivo de control de procesoque está concetado en un bucle de control de proceso durante elfuncionamiento de un proceso incluye un controlador de conmutacion, un generador de senaes, un conmutador, un mecanismo acumulador de respuestas, y unmecanismo analizador. El controladorde conmutacion monitorea una senal de proceso durante el funcionamiento del proceso para determinar si la senal de procesoes substancialmente estable. En el caso de que la senal de proceso sea substancialmente estable, el conmutador reemplaza unasen al de control por una senal deensayo de diagnostico generada por el generador de senales. El acumulador de respuestas está en comunicacion con el bucle de control de proceso para obtenerindicacion de la respuesta del dispositivo de control deproceso a la senal de ensayo de diagnostico. Entonces la unidad analizadora determina el parámetrodel dispositivo a partir de la senal de ensayo y la indicacion de respuesta.
