PROPORTIONAL CONTROLLER
PROPORTIONAL CONTROLLER
AIM: To design
analog proportional controller for different gain values.
EQUIPMENTS AND COMPONENTS:
Op-amp, resistors, connecting wires,
CRO, power supply etc
THEORY:
In
this experiment the proportional controller is the upgraded version of the
ON-OFF controller. It is a linear feedback controller system, which is applied
to the controlled variable which is proportional to the difference of the set
point and the measured value or process value the output is the multiplication
of the error signal and the proportional gain and the controller output at two
error.
