Controlled systems without
compensation
Controlled systems with an amplification factor to infinite are
called controlled systems without compensation because of
their integrating behaviour. It means that the controlled variable
continuously grows after a change of the variable or due to
interference. It therefore never reaches a final value.
These controlled systems are called I(ntegral) systems.
Controlled system with delay
Most controlled systems are a series connection of P systems
(systems with compensation) and one or several T
1
systems
(systems with inertia). A first level controlled systems is e.g.
created by connecting a restrictor and a subsequent memory.
In controlled systems with delay the controlled variable
responds to a change of the variable only after a delay T
t
. The
delay T
t
or the sum of T
t
+ T
u
is the measure for the possibility to
adjust the system. The bigger the T
q
/ T
u
ratio the better the
possibility to adjust the system.
The controllers integrated in the library are a summary of the
presented basic functions. The functions used and their
combination depend on the controlled system.
