Hello,
I have a heat transfer as follows:
a coil with steam heats a tank of soda. There is a control loop. I have a temperature instrument and according to this a control valve opens so that the desired temperature has to be in the tank according to how much steam is enters the coil or not...
I am dealing with a pid controller which has to regulate a flow as follows:
Set Point: 60 mc/h
Manipulated variable is a flow control valve.
Now, in practice I have noticed that the reaction time is very slow. Considering I can make a tunning and I can change, the "gain", the "integration...
