Abstract:
State observers employed in the analytical redundancy approach can generate redundant signals. As the sensor has noise in its measures, this noise also affects the redundant signal. In this paper, we will show how the noise in the sensor signal can affect the redundant signal, generated for a bank of observers in a DOS structure, and some simulations results of this signal and finally we will do some considerations in the state observers design to reduce the noise level at the redundant signals.
