Based on fuzzy control and sliding mode observer technique, a fault accommodation strategy is proposed for near space hypersonic vehicle (NSHV) with actuator fault in this study. Firstly, the Takagi-Sugeno (T-S) fuzzy model is implemented to represent the NSHV nonlinear dynamics, and a bank of sliding mode observers are designed for the established T-S model, which are used to generate the resi...
Studies on the seismic response of skewed integral abutment bridges have mainly focused under far-field non-pulse-type ground motions, yet large amplitude and long-period velocity pulses in near-fault motions might significant impacts bridge response. In this study, nonlinear dynamic an (SIAB) pulse far-fault non-pulse type are analyzed considering soil–structure interaction, along with paramet...
In analog circuits, process variations result in physical parameter variations. Simulated values must then be considered with there tolerance intervals. Consequently, contrarily to digital circuits where the outputs are either '0' or '1' such that we can decide without ambiguity whether a fault is detectable or not, for analog circuits the fault detectability is a vague problem as the fault can...
The paper presents a concept of single event equivalence to be used in the sequential circuit fault simulator. The concept dynamically identifies the equivalent faults for a simulated pattern. It combines advantages of the fanout-free region, critical path tracing and the dominator concept, which were applicable only to combinational circuit fault simulation. The implemented fault simulator, SE...
The main reservoir in the Dixie Valley geothermal field of Nevada is hosted in fractured Jurassic rocks within the hanging wall of the Stillwater fault. Within the Jurassic sequence, at least four major stages of alteration related to the fault system can be identified. The paragenetic sequence from oldest to youngest consists of Stage I) biotite-potassium feldspar veins, and epidote-chlorite-c...
Fault simulation constitutes an indispensable tool in ensuring the correctness and quality of manufactured digital designs. Traditional uniprocessor based algorithms for fault simulation have been observed to be agonizingly slow for today's large and complex digital designs. More recently, a few researchers introduce an approach, as evident in the literature, wherein the fault set is partitione...
Repeated seismic surveys of the Landers, California, fault zone that ruptured in the magnitude (M) 7.5 earthquake of 1992 reveal an increase in seismic velocity with time. P, S, and fault zone trapped waves were excited by near-surface explosions in two locations in 1994 and 1996, and were recorded on two linear, three-component seismic arrays deployed across the Johnson Valley fault trace. The...
Study on the fault diagnosis method through the combination of decision classification algorithms and expert system. The method of extracting diagnosis rules with the CTree software was given, and a fault diagnosis system based on CLIPS was developed. In order to verify the feasibility of the method, at first the sample data was got through the simulations under fault of direct-drive wind turbi...
The design of a fault tolerant system would be enhanced if a rapid prototyping approach could be conceived which allows fault tolerance to be modelled quickly, and faults simulated to analyse the behaviour of the system. This paper concentrates on how a functional specification language, and its environment, can be used to describe and investigate the properties of parallel fault tolerant syste...
This paper has made a qualitative and quantitative analysis by establishing the tunnel fault tree and giving the minimal cut sets of the faults in tunnel, and tested the data in tunnel combined with artificial neural network. The fault detection mechanism in this article has been simulated by MatLab and processed a lot of the actual data through the tunnel operating history. Experimental result...
