  • Page 91 6.3 Adjusting PID Manually Description Description and Tuning of Proportional Band The proportional band is defined as the amount of change in input (or deviation), as a percent of span, required to cause the control output to change from 0% to 100%. Because a narrower proportional band gives greater output change for any given deviation, it therefore also makes the control performance more susceptible to oscillation.
  • Page 92 6.3 Adjusting PID Manually Description and Tuning of Integral Time The integral action (I action) is a function that will automatically diminish the offset (steady-state deviation) that is inherently unavoidable with proportional action alone. The integral action continuously increases or decreases the output in proportion to the time integral of the deviation (the product of the deviation and the time that the deviation continues.) The integral action is normally used together with proportional action as proportional- plus-integral action (PI action).
  • Page 93 6.3 Adjusting PID Manually Description and Tuning of Derivative Time If the control object has a large time constant or dead time, the corrective action will be too slow with proportional action or proportional-plus-integral action alone, causing overshoot. However, even just sensing whether the deviation is on an increasing or a decreasing trend and adding some early corrective action can improve the controllability. Thus the derivative action (D action) is action that changes the output in proportion to the deviation derivative value (rate-of-change).
  • Page 94 6.3 Adjusting PID Manually Manual PID Tuning Procedure (1) In principle, auto-tuning must be used. (2) Tune PID parameters in the order of P, I, and D. Adjust a numeric slowly by observing the result, and keep notes of what the progress is. (3) Gradually reduce P from a larger value. When the PV value begins to oscillate, stop tuning and increase the value somewhat.

This function is called “reference deviation.” In the fixed point control, if the actual amount of deviation exceeds the setpoint of the reference deviation, the controller automatically changes to the PID parameter group (PID of group R) set for the zone. If the actual amount of deviation becomes smaller than the setpoint of reference deviation, the controller changes to the PID parameter group appropriate for the zone.

Hunting means the PV becomes unstable and oscillates around SP. SUPER2 = ON Hunting ● In hunting condition, the Super2 function selects the output from process model as PV signal. ● The process model removes a factor of dead time from the actual process. ● The real process is under the open-loop condition. ● After hunting is suppressed, the Super2 function selects real PV signal, and carry out the standard feedback control.

To avoid this, the controller provides an anti-reset wind-up function for suppressing an extreme integral output by stopping PID computations.
