In this work we study a new approach of fault tolerant control schema.The suggested strategy is an active Fault Tolerant Control (FTC) strategy that reconfigures the controller on-line taking into account changes due to the faults where both the block of fault detection and the block of the controller are formulated as a Linear Matrix Inequality (LMI) problem. The problem of fault estimation is...

Fault Injection Attacks are a powerful form of active attack mechanism which can threaten even the strongest of cryptographic algorithms. This attack vector has become more pertinent with the growing popularity of the Internet of things (IoT), which is based on small omnipresent embedded systems interacting with sensitive data of personal or critical nature. This tutorial addresses this issue o...

This paper addresses the development of a novel Active Fault Tolerant Control Scheme (AFTCS) which, when used with an independently designed guidance system, turns out to give an overall fault tolerant guidance and control system. This AFTCS methodology avoids a logic-based switching controller by exploiting an adaptive fault estimator whose design is based on the Non Linear Geometric Approach ...

There are two active faults, i.e., the Chinshan and Shangjiao faults in the Taipei Metropolitan Area. The moment magnitude (M), maximum displacement (Dmax), and average displacement (Dave) of potential earthquakes, which would rupture the two faults, are evaluated. The fault lengths are 25 and 20 km, respectively, for the Chinshan and Shangjiao faults. The optimum values of the three parameters...

An active sensor fault compensation control law is developed for a class of nonlinear systems to guarantee the closed-loop stability in the presence of a fault, based on a fuzzy logic system and sliding mode. Through the adaptive process of the parameters, the dynamics caused by the fault is counteracted. The fuzzy sliding mode control is introduced to attenuate the fuzzy approximation error. S...

Data from 10,126 earthquakes that occurred in the southern California region between 1934 and 1963 have been synthesized in the attempt to understand better their relationship to regional geologic structure, which is here dominated by a system of faults related mainly to the San Andreas system. Most of these faults have been considered "active" from physiographic evidence, but both geologic and...
