I am using the PID library and the PID-AutoTune library to tune a system which is slow temperature monitoring system. It takes about 1 and half hours to get to set temperature.
When I am using the library it stops tuning after a few minutes and set the variables.
I have basically changed nothing in the library and using the example in the library to tune it. I have change the input ( to my temp probe) , setpoint to my target temp , the output to my heatsource and the gain values to my manual tune values.
To those who have used the library previously could you give any input into how I could tackle this situation.
Thanks in advance
