To tackle problems of on-line fault detection in industrial process system, a method based on modified SVDD (support vector data description) is presented. Since the performance of SVDD is strongly influenced by kernel parameter selection and hyper-sphere class-boundary. A new criterion is presented to optimize the kernel parameter, which is performed by measuring the non-Gaussian value of kernel...
Wireless sensor networks distributed signal processing has to operate under stringent energy and bandwidth limitations. Usually, the observations need to be quantized before they are sent to fusion center (FC). This paper we introduce a multiple bits distributed moving Horizon state estimation approach based on a multiple state single output Gaussian-Markov model. Each sensor node has a thresholds...
Obtaining the transformer internal parameters exactly for physical model based transformer protection is difficult because of the complex electromagnetic relation of the transformer, exemplified by transformer protection method based on the loop equation principle. According to the approaching ability of the artificial neural network, using artificial neural network to approach the electromagnetic...
