According to the complexity of turbine on power plant, a kind of fault diagnosis method based on information fusion is proposed in this paper. Multi-sensor data is adopted and D-S evidence theory is applied, thus the uncertainty of information can be effectively overcome. Considering the data credibility of various information sources, the data fusion method is applied to the simulation experim...

Some people suffering from diabetes use insulin injection pumps to control the blood glucose level. Sometimes, the fault may occur in the sensor or actuator of these pumps. The main objective of this paper is controlling the blood glucose level at the desired level and fault-tolerant control of these injection pumps. To this end, the eligibility traces algorithm is combined with the sliding mod...

For a typical MIMO (Multiple-Input Multiple-Output) nonlinear dynamic system, fault detection and isolation usually aim at process faults with an assumption that actuator faults and sensor faults do not occur at the same time, which is not always the case. This paper uses Extended State Observer for real-time process fault detection and fuzzy inference for fault isolation. It then investigates ...

This paper addresses the optimum design of fault detection systems based on sensor location. A multi-objective optimization problem based on optimal sensor location for fault detection is formulated for linear time invariant system. Measurement outputs are formed by selecting m variables of N available process measurements that ensures a high fault detetion performance. A minimum total measurem...

In this paper, fault tolerant compensation for non-linear plants is addressed. Soft fault detection and isolation is performed for a partial sensor fault detection. New method is proposed that combine model predictive controllers with fuzzy Takagi-Sugeno models. An example is presented that illustrates the functionality of the proposed method. Keywords— Fault tolerant control, Fault detection a...

Coverage conservation and extend the network lifetime are the primary issues in wireless sensor networks. Due to the large variety of applications, coverage is focus to a wide range of interpretations. The applications necessitate that each point in the area is observed by only one sensor while other applications may require that each point is enclosed by at least sensors (n>1) to achieve fault...

The potential gains of deploying sensor networks for large scale applications are being realized. One of the basic operations in sensor networks is in-network aggregation. Among the various approaches to in-network aggregation, such as gossip and tree, including the hash-based techniques, the tree-based approaches have better performance and energy-saving characteristics. However, sensor networ...
