I want to understand how these constants of P , I and D affect.
I am using an NTC thermister 100k as temperature sensor. The sensed temperature is lesser than the set temperature at 12 V (about 1 deg Celcius)
and when 7.5 Volts is given to the heater then the temoerature sensed is 3-4 degrees less. Can I caliberate this for better reading with the help of these constants??
Thanks for your help.
