In order to effectively solve the risk of safety on power window, an improved pinch detection algorithm based on the fault detection observer estimation is proposed for an anti-pinch window control system. In designing a residual generator, the proposed fault detection algorithm makes use of the pinch torque rate information by establishing the mathematical model of DC, considered as a fault un...

—The increasing number of Electro within the network of a vehicle is increa complexity of these networks. Thus, fault sophisticated systems becomes more complex paper is to provide a technique to enable detection in a premium vehicle network or a which uses the Controller Area Network (C communication. The fault detection technique based on a sequential behaviour of the CAN n and by using signa...

An unknown input high gain observer based parametric fault detection and isolation scheme is presented. First, a reduced order unknown input high gain observer is derived. Then, using these observers, a fault detection and isolation technique is devised to detect and isolate the parametric fault of a system whose parameters are uncertain to some extent. The proposed FDI algorithm consists of tw...

In this paper we present a fault-injector tool, named JAFL (Java Fault Loader), which was developed with the target of testing the fault-tolerance mechanisms of Grid and Web applications. Along with the JAFL internals description, we will present some results collected from synthetic experiments where we used both our injector and fault detection mechanisms. With these results we expect to prov...

In this paper, a novel technique is applied to detect fault in the transmission line using wavelet transform. Three phase currents are monitored at both ends of the transmission line using global positioning system synchronizing clock. Wavelet transform, which is very fast and sensitive to noise, is used to extract transients in the line currents for fault detection. Fault index is calculated b...

Many fault detection methods have been proposed for monitoring the health of various industrial systems. Characterizing the monitored signals is a prerequisite for selecting an appropriate detection method. However, fault detection methods tend to be decided with user's subjective knowledge or their familiarity with the method, rather than following a predefined selection rule. This study inves...

This paper presents a fault detection, diagnosis, and reconfiguration method based on support vector machines. This method is appropriate for certain or predetermined faults and involves a fault detection and diagnosis unit and an online controller selection type reconfiguration mechanism. In this method, when a fault is detected and diagnosed by the fault detection and diagnosis unit, a suitab...

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 ...

Renewable energy sources are gaining high prominence in today’s world. However, these sources do not supply energy throughout the year and hence efficiency is required when extracting energy from them. Wind energy is a recently developing area of common interest. Efficiency of a wind turbine is however, very low. Hence, detection of fault in the system becomes very essential so as to increase t...

Building efficient systems is one of the main challenges for software developers, who have been concerned with dependability-related issues as they built and deployed. Lots of changes often needs including the nature of faults and failures and the complexity of systems. Sometimes accepting minor errors always need efforts to eliminate faults that might cause them is in the core of dependability...
