A fault diagnosis and tolerant control method for aerospace relay with environmental disturbance

چکیده
The aerospace relay is an important part of the complex electronic systems in large-scale structural components, such as launch vehicle, and its working state determines whether system can work properly. Due to lack high-value samples, complexity system, multiple environment disturbance factors affecting relay, this study, we developed a new fault diagnosis tolerance control framework for based on belief rule base with attribute reliability (BRB-r). In proposed framework, develop model BRB-r analyze monitoring characteristics divide into categories: normal function, defective loss function. Then, provide three respective strategies these states: maintain original input, reconfigure rate, switch relay. We demonstrated performance experiment using JRC-7M test laboratory.

Fault-Tolerant Control of a Nonlinear Process with Input Constraints
A Fault-Tolerant Control (FTC) methodology has been presented for nonlinear processes being imposed by control input constraints. The proposed methodology uses a combination of Feedback Linearization and Model Predictive Control (FLMPC) schemes. The resulting constraints in the transformed process will be dependent on the actual evolving states, making their incorporation in the de...
متن کاملFault Diagnosis and Fault-Tolerant Control of Wind Turbines via a Discrete Time Controller with a Disturbance Compensator
This paper develops a fault diagnosis (FD) and fault-tolerant control (FTC) of pitch actuators in wind turbines. This is accomplished by combining a disturbance compensator with a controller, both of which are formulated in the discrete time domain. The disturbance compensator has a dual purpose: to estimate the actuator fault (which is used by the FD algorithm) and to design the discrete time ...
متن کاملFault Diagnosis and Fault Tolerant Control Using Reduced Order Models
The present work considers a model reduction approach for fault diagnosis with generalised likelihood ratio (GLR) method to improve upon its diagnostic performance and computational efficiency in large dimensional applications. Model reduction techniques are widely used in controller design. A similar concept with balanced truncation technique is employed to obtain a reduced order diagnostic mo...
