The measurable disturbances in superheated processes are input to the neuro- PID controller besides the sequences of tracking error in outer loop control system, hence, feedback control is combined with feedforward control in the proposed neuro- PID controller.

The autotuning procedures on simulated controlled object and PLC controller without build-in autotuning were tested. Given the registration of types and the proposed syntactical rigidness of the value, guaranteed by the schema, together with the use of PIDs in subject and predicate, the type concept has the ability to overcome the fuzziness and lack of reliability of semantic web categories with its URL references and possibly changing locations and content.
