How to correctly use Self Tune FB?
Hi there,
I am haveing a bit of confuse trying to use selftune function block.
I was trying to tune a tempreature loop but it is quite a bit tricky. the loop is for controlling condensation ratio of chemical processing factory.
The first loop is for jacket and internal of the vessle. it can be tuned with ease, however the loop that control condensation is quite hard to tune. First i must wait for the first two loop to reach steady state. When condensation start, the condensor loop will have to try to keep a steady tempreature for the process to have consistancy.
The condensation process mean that the loop before condensor will loose quite a bit of heat and will render the loop of jacket to start oscilating. When the jacket of this vessle oscilate it also cause the condensor loop to oscilate.
How Do I use the sefltune function block correctly?
Are there a standard steps to follow?
