1. Trying to write PID control for temperature maintain in oven. We are doing it Pb,Ti & Td.
2. Now I see sometimes I am able to maintain temperature to setpoints.
3. Problem happens when intergral grows to large values. I am reading on internet there are many ways available. I tried clamping method to try clamp to some values, but it dont work, for some cases it work and some it dont, i.e for every setpoint clamp value is different to maintain temperature. Higher the setpoint higher the clamp value required.
Currently I am doing by hit and trial, but its not final solutions
4.Any one have experiecne which methods work best for this type of applicaiton?
5. I have seen two most common are:
a) Back calculations: but found most of matlab implementations, trying to find c implemenation
b) second is this: but dont know how to calculate AR band
c) Any other better method?
