The work presents some results concerning a fault detection scheme for dynamic processes using disturbance decoupling technique. The first step of the considered approach consists of exploiting input-output descriptions of the monitored system.

The next step of the scheme leads to define a set of parity relations that can be used as residual signals since they are insensitive to the disturbance term.

Abstract

The work presents some results concerning a fault detection scheme for dynamic processes using disturbance decoupling technique. The first step of the considered approach consists of exploiting input-output descriptions of the monitored system. In particular, the disturbance term of that model can be used to take into account unknown inputs affecting the system. The next step of the scheme leads to define a set of parity relations that can be used as residual signals since they are insensitive to the disturbance term. The proposed fault detection procedure has been tested on an industrial process simulator. Sensor and actuator faults have been simulated on a gas turbine model. Simulation results and concluding remarks have been finally reported.
