In order to prevent machine malfunctions and to determine machine operating state, it is necessary to use correct measurements from actual system inputs and outputs. In this paper, an approach based on analytical redundancy is suggested to solve the sensor fault detection and isolation problem in a single-shaft industrial gas turbine. The presented method requires the generation of classical residual functions obtained by different observer configurations. The diagnosis is performed by checking fluctuations of these residual caused by faults.
