Identification of Fuzzy Relational Models for Fault Detection
This paper presents the concept of fuzzy relational models for use in a fuzzy output estimator. A suitable "eld of application is in fault diagnosis, where output observation rather than state observation is needed for the generation of fault re#ecting residual signals. Due to their non-linear structure, fuzzy relational models can be used appropriately for building models of non-linear dynamic...
متن کاملUAV attitude Sensor Fault Detection Based On Fuzzy Logic and by Neural Network Model Identification
Fault detection has always been important in aviation systems to prevent many accidents. This process is possible in different ways. In this paper, we first identify the longitudinal axis plane model using neural network approach. Then based on the obtained model and using fuzzy logic, the aircraft status sensor fault detection unit was designed. The simulation results show that the fault detec...
متن کاملFuzzy Relational Matrix-Based Stability Analysis for First-Order Fuzzy Relational Dynamic Systems
In this paper, two sets of sufficient conditions are obtained to ensure the existence and stability of a unique equilibrium point of unforced first-order fuzzy relational dynamical systems by using two different approaches which are both based on the fuzzy relational matrix of the model.In the first approach, the equilibrium point of the system is one of the centers of the related membership fu...
متن کاملUsing Fuzzy Relational Models for Control
In this paper the use of Fuzzy Relational Models (FRMs) for model-based process control is investigated. The work presented here is centred around the development of a Fuzzy Internal Model Controller (FIMC) for a simulated multi-variable pH process. The paper begins with a brief introduction which sets the scene for the work. There then follows a description of the pH process and the particular...
متن کاملFuzzy Expert System for Gyroscope Fault Detection
Gyroscopes are instruments capable of sensing changes in their inertial orientation. A gyroscope has one or more sensitive axis and can measure a rotation around them. They are usually mechanical devices that employ a rapid spinning mass to detect the inertial variations. Satellites usually have gyroscopes in the Attitude and Orbit Control System as attitude (orientation) sensors that measure a...
