Manual setting of the control parameters without knowledge of the system behavior
The control parameters for optimum control of the system are not yet known in this case. To
keep the control loop stable in any case, the following factory settings must be made (the
values apply for both parameter sets):
Proportional action factor Kp
=
0.1
Readjustment time
Tn
=
9984 s
Derivative action time
Tv
=
oFF
- P--controller (control signal P
*
= high)
- Set the desired setpoint and set the control difference to zero in manual mode.
- The working point required for the control difference zero is set automatically at Yo =
AUto (factory setting) in manual mode. The working point can also be entered manu-
ally by setting the online parameter Yo to the desired working point.
- Switch to automatic mode.
- Increase Kp slowly until the control loop tends to oscillate due to slight setpoint
changes.
- Reduce Kp slightly until the oscillations disappear.
- PD--controller (control signal P
*
= high)
- Set the desired setpoint and set the control difference to zero in manual mode.
- The working point required for the control difference zero is set automatically at Yo =
AUto (factory setting) in manual mode. The working point can also be entered manu-
ally by setting the online parameter Yo to the desired working point.
- Switch to automatic mode.
- Increase Kp slowly until the control loop tends to oscillate due to slight setpoint
changes.
- Switch Tv from oFF to 1 s.
- Increase Tv until the oscillations disappear.
- Increase Kp slowly until oscillations reappear.
- Repeat the setting according to the two previous steps until the oscillations can no
longer be eliminated.
- Reduce Tv and Kp slightly until the oscillations are eliminated.
- Pi-controller (control signal P
*
= Low)
- Set the desired setpoint and set the control difference to zero in manual mode.
- Switch to automatic mode.
- Increase Kp slowly until the control loop tends to oscillate due to slight setpoint
changes.
- Reduce Kp slightly until the oscillations disappear.
- Reduce Tn until the control loop tends to oscillate again.
- Increase Tn slightly until the tendency to oscillate disappears.
- PiD-controller (control signal P
*
= Low)
- Set the desired setpoint and set the control difference to zero in manual mode.
- Switch to automatic mode.
- Increase Kp slowly until the control loop tends to oscillate due to slight setpoint
changes.
- Switch Tv from oFF) to 1 s.
- Increase Tv until the oscillations disappear.
- Increase Kp slowly again until the oscillations reappear.
