7.15.3.1 Procedure for setting the control parameters for internal control
1. Choose a set of control parameters from the table of control parameters (
þ
7.15.3.2).
2. Adjust the setpoint by 5 °C (5 K setpoint step change) and record the outflow temperature for
at least 5 minutes.
3. If the outflow temperature oscillates (>0.1 K), then enlarge Xp until the oscillation dies
away. Always wait a number of minutes between the changes.
4. +20 K setpoint step change, await transient response,
-20 K setpoint step change, await transient response.
5. Assess transient responses:
- if an overshoot is to be reduced, then slowly increase Tv (until about 90 % of Tn),
- if settling is too slow, then reduce Tv to about 60 % of Tn,
- always adjust Td:
Td = 20 % of Tv,
- after each change repeat Point 4. Carry out and evaluate ±20 K setpoint step changes.
6. If the response takes too long, then Tn can be reduced. Similarly reduce Tv, Td as a per-
centage. Reduce Xp to 70...50 % so that the system oscillates. Then continue from Point 2.
7. If the tendency to oscillate increases without the overshoot being acceptably reduced, then
a) Xp can be slightly increased; continue with Point 3,
b) larger time constants should be chosen: Increase Tn , Tv , Td by 30...80 %,
and Xp to 70...50 % so that the system oscillates. Then continue from Point 2.
