DERIVATIVE CONTROLLER
DERIVATIVE CONTROLLER
AIM: To design
the analog proportional derivative controller using Op-amp
EQUIPMENTS AND COMPONENTS:
Op-amp, resistors Pot, connecting
wires, function generator etc
THEORY:
The
derivative controller mode gives a controller additional control action when
the error changes consistently. It also makes the loop more stable which allows
higher controller gain and faster integral action.
The
effect of reducing the maximum derivation from the process set point if the
process receives and external disturbance, for the typical temperature control
loop, you can expect 20% reduction in the maximum deviation.
