reset windup in integral control is using for removing
offset between process variable and setpoint. After
specific time it produe more signal to minimize the offset.
in pneumatic case
Extra signal depends on integral setting.MPR and RPM
due to reset windup controller output 'll goes equal to the
supply pressure (1.4 kg/cm2)or equal to dead zero (0
kg/cm2. Means cross the limmit (0.2 to 1 kg/cm2).
To keep in under limmit (0.2 to 1 kg/cm2) of controller
output normaly using anti reset windup.
