Q

Parametri (funzionali)

A

Forniscono le caratteristiche statiche del sistema considerato. Ad esempio dei parametri per un sistema vite-madrevite sono l’angolo del filetto, il diametro medio del filetto, la lunghezza della vite ecc

Q

Variabili

A

Forniscono le caratteristiche dinamiche del sistema, ovvero quelle che variano nel tempo.
Le variabili possono essere di input (fornite dall’esterno al sistema (sottosistema o componente)
Output: dal sistema vengono fornite all’esterno o ad un sottosistema o componente
Stato: misurano quanta energia/materia/dati sono stati immagazzinati dal sistema nel tempo

Q

Stato del sistema

A

The state of the system represent knowing the state of the system in precise time. Knowing the global state of the system means to know the state of the system in each time instant (for example the mesurament of the energy embodied by the system). So knowing that means to know the relationship among input and output. That relantionship is made by the use of parameters, that are involved in the description of the state

Q

System classification by parameters

A

Could be:
Stationary, if the parameters remain constant in determinated time window
Variant, if change over time
