Answer Posted / welcome4ujd
By adding the reset action to the proportional action the
controller produces a larger output for the given error
signal and causes a greater adjustment of the
control valve. This causes the process to come
back to the setpoint more quickly. Additionally,
the reset action acts to eliminate the offset error
after a period of time. Reset Windup Proportional plus
reset controllers act to eliminate the offset error found
in proportional control by continuing to change the output
after the proportional action is completed and by returning
the controlled variable to the setpoint. An inherent
disadvantage to proportional plus reset controllers
is the possible adverse effects caused by large
error signals. The large error can be caused by
a large demand deviation or when initially starting up
the system. This is a problem because a large sustained
error signal will eventually cause the controller to drive
to its limit, and the result is called "reset windup."
Because of reset windup, this control mode is not well-
suited for processes that are frequently shut down and
started up.
