Abstract

This paper present a method to detect the transducers fault in the close loop control systems. The necessities imposed for the fault detection algorithm are: rapid answer in the case of fault, which comes out; the diminution of the risk to come out false alarms; lower effort calculation. In the paper are presented the equations of fault detection structure that suggest the software algorithms. In last part of the paper, the algorithm was verified on the steam overhead equations, developed in this paper.
