Resumen : | This paper introduces the probabilistc radial function network (PRBFN) and a new incipient fault detection system based on it. The PRBFN is a neural network model able to estimate IO mappings and probability density functions. These capabilities play a crucial role in the design of the proposed fault detction system, where faults are detected by comparing the actual behaviour of the plant with the predicted using a model of normal operation conditions. Once the reliable domain of the model has been defined, a comparison is made through a local estimation of the upper bound of the resulting residual under normal operation conditions. This procedure automatically adjusts the sensitivity of the fault detction system to the intrinsic characteristics of the underlying process and prevents false alarms by detecting unknown operating conditions. |
