•

Due to the gain changes that occur at

the transition from ramp to soak,
conventional controls are inevitably
prone to overshoot. Yet, if the PID
constants are set so that the output
stabilizes more quickly in order to avoid
overshoot, the temperature ramp will lag
behind the prescribed pattern.

•

By using the "SUPER" function, the

temperature up ramp can be made to
follow the pattern almost exactly, and
significant savings can be achieved.

Example of ramp to soak transition overshoot suppression control

Process: Small electric furnace

P = 1.8%

I = 317 sec

D = 79 sec

•

The "SUPER" function is extremely

effective for improving response to
disturbances. The overshoot
experienced with conventional PID
control in correction for disturbances is
significantly reduced, and settling time is
greatly speeded up.

Example of overshoot suppression control on response to disturbances

Process: Kiln
