| dc.description.abstract | Neural computing is one of the fastest growing branches of artificial intelligence. Neural Nets, endowed with inherent parallelism hold great promise owing to their ability to capture highly nonlinear relationships. This paper discusses the use of the back propagation neural net for failure cognition in chemical process systems. The backpropagation paradigm along with traditional fault detection algorithms such as the finite integral square error method and the nearest neighbor method are discussed. The algorithm is applied to an IMC controlled first order linear time invariant plant subject to high model uncertainty. Compared to traditional methods, the backpropagation technique is shown to be able to accurately discern the supercritical failures from their subcritical counterparts. The use of backpropagation fault detection systems in on-line adaptation of nonlinear plants has been investigated. | en_US |
