Abstract:A type of intelligent temperature controller system, with self-tuning function for PID parameters, which
s controlled by PID, is stated. First the realization of the system is presented, then the artful principle of the self-tuning
algorithm and the A/D converter and the design of software are introduced in detail. A brief outline of the implementa-
ion is discussed last.
