C(t) T1 T2 t
The physical systems existing in our process industries have their dynamic response, represented by variations of control signals over time based on given input signals. Regarding an impulse input for a system that does not have complex poles, the time response can be characterized as illustrated in the figure below. Therefore, it is correct to state that:
alternatives:
a)The time response of physical systems cannot be described graphically.
b) Time is a response that the process operator perceives, and this is not a characteristic of physical systems.
c) The system's response does not depend on time, but on the characteristics of the raw materials and their quantities.
d) The response curve of a system cannot describe its characteristics.
e) The curve indicated in the figure represents two time constants, the first (t1) being a delay time constant.
