Wireless Sensor Networks (WSNs) consist of many low cost and light sensors dispersed in an area to monitor the physical environment. Event detection in WSN area, especially detection of multi-events at the same time, is an important problem. This article is a new attempt for detection of two simultaneous events based on distributed data processing structure(More)
In this paper, a fault detection and isolation system for nonlinear systems is presented. Fault detection and isolation is accomplished by using extended state observer (ESO) and fuzzy logic system. The major of observer-based fault detection methods rely on the accurate mathematical model of the system, but in the real world an accurate model of the system(More)
Lack of timely fault detection by the user in sensitive systems, will cause damage and loss of significant amounts of resources and information. This paper presents the fault detection and isolation (FDI) in singular bilinear systems with unknown input disturbances and faults by using bilinear sliding mode observer. For this purpose, firstly, the singular(More)
