2.3. Characteristics

Controlled systems in which a new constant output value sets itself after a certain time has passed are called 'self-regulating process’.

The relationship of the output variables to the input variables in the steady state results in a characteristic.

Parameter

In the environment of an operating point, the characteristic is replaced with a tangent. In the environment of an operating point, the problem is treated as a linear problem.

The zero point of the variables x(t), y(t) and z(t) refers to the operating point A:

:

x = X – Xo y = Y - Yo z = Z - Zo
