Abstract: In this paper is presented a possibility of control of the electrical resistance furnace temperature. It is been considered that this process can be very well approximate taking into consideration that the heating process model is of a delayed time constant system of first order.
To determine the values of the process parameters of the analogical system function of the process, she was approximate with a digital system function of the process of which parameters can be determined in an adaptive manner. Based on these values, the values of the process parameters of the analogical system can be computed, also in an adaptive manner.
The process controller parameters are computed based on the values of the process parameters of the analogical system and according to some criteria. The criteria, which can be used in choosing the delayed time controllers, are criteria based on stability limits method, criteria based on identification result and experimental criteria determined with process in functioning.
From the earlier presented here result that the temperature control process is realized using adaptive filter in identification scope.
Because the temperature measured process is very disturbed by noise it was used an adaptive filter ALMS (Average Least Mean Squares) in scope of noise cancellation.
Finally are presented the advantages of the proposed temperature control method comparative to other.
