Trick for this month : Synchronization?
In some processes, it is essential to synchronize loops. For example:
- when products are mixed together in a reservoir or in a static mixer;
- when an additive is added at a certain percentage of flow;
- when different parts of a process have to reach a specific value at the same time;
- etc.
When synchronizing loops, the following steps should be followed :
- verify equipments, especially the transmitter, input/output, valve or variable speed drive;
- ensure the process is linear; if not, the speed will vary accordingly to the measurement or the controller output;
- identify by tests which loop is the slowest;
- tune the slowest loop accordingly to the performance criterion selected;
- tune the other loops at the same speed.
If a performance monitoring software is used, not only usual performance indices must be used, but another indice must be added to the loop health; for each loop, the settling time will be monitored to ensure the loop remains at its speed. If the speed varies, a flag will be raised to notify that the loop does not perform anymore.
