Experimental Autotuning proportionalintegral-
derivative (PID) Temperature Control of Oven
Using Microcontroller is presented in this paper. Different
types of autotuning PID controller methods have been
applied to the oven designed as an experiment set. This
experiment set is an FODPT (First Order Plus Dead Time)
system. Relay (PI, PID) and integral square time error
criterion (ISTE) set point (PI, PID) are used as autotuning
PID method. To be able to control this system a digital
signal processing card is designed using PIC 17C44 as
microcontroller and ADS1212 as A/D converter. And the
results are discussed to define which controller is the best
for the oven.
