PID problem again

Started by ricinecwh July 22, 2006
My projectis the temperature control by using PID writing in the basicX.

I had asked this question before, and get the method to find the three
values P, I, D out. However, my professor do not satisified that it is only a
method of "try and error" although it is accurate.

He want me to find a method that can find the three values out without
"try and error".
Is it possible??
