Sensor Validation for Structural Systems with Additive Sensor Faults

Sensor Fault Detection for a class of Uncertain Nonlinear Systems Using ‎Sliding Mode Observers

This paper deals with the issues of sensor fault detection for a class of Lipschitz uncertain nonlinear system. By definition coordinate transformation matrix for system states and output system, at first the original system divided into two subsystems. the first subsystem includes uncertainties but without any sensor faults and the second subsystem has sensor faults but is free of uncertaintie...

Robust Takagi-Sugeno sensor fault tolerant control strategy for nonlinear system

Intelligent Sensor Fault Detection and Identification for Temperature Control

This paper addresses artificial intelligence and signal processing based online fault detection and identification. Fuzzy logic controller has been utilized for temperature control. Faults often cause undesired reactions, so to keep the system stable and to obtain an acceptable control performance is an important problem for control system design. In this paper, a multiplicative, an additive an...

Inter-Sensor Validation for Improved Reliability of Multi-Sensor Systems

Modern day personal navigation devices are often realized as a multi-sensor integrated navigation system wherein the measurements from various sensors are combined to generate a navigation solution. A fault occurring in any of these sensors can affect the performance of the navigation system, potentially compromising the reliability of the navigation solution. It is thus imperative to detect an...

An LPV Approach to Sensor Fault Diagnosis of Robotic Arm

One of the major challenges in robotic arms is to diagnosis sensor fault. To address this challenge, this paper presents an LPV approach. Initially, the dynamics of a two-link manipulator is modelled with a polytopic linear parameter varying structure and then by using a descriptor system approach and a robust design of a suitable unknown input observer by means of pole placement method along w...
