Continuous controller (PID)
With continuous controllers, the manipulated variable Y assumes any
value within a working range.
l
P controller: The P controller changes the manipulated variable immediately
proportionally to the change in the control deviation.
l
I controller: The I controller (integrator) assigns a particular control rate to a
particular control deviation.
l
PI controller: The PI controller is formed by combining a P controller with an I
controller. The PI controller contains a proportional and an integral term.
l
PD controller: The controller comprises a controller with a P term and a D
term. The derivative element assigns a manipulated variable to a particular
change rate of the control deviation.
l
PID controller: The manipulated variable consists of a proportional, an integ-
ral and a derivative term.
