Failure diagnosis of a cement kiln using expert systems

The supervisory control and the fault diagnosis of a cement kiln is presented in this paper. The fault diagnosis system has been developed using state space and sensor space mapping, following the methodology developed by the authors. In this case, the mentioned methodology has lead to the use of an expert system implemented as a fuzzy logic fault diagnoser. Practical results of the implementation of the proposed supervisory control and fault diagnosis system in a cement kiln are included in the paper.
