A fault-tolerant control method for distributed flight control system facing wing damage

Design of Fault Tolerant Flight Control System

The purpose of the paper is to present an approach to detect, isolate and accommodate the sensor or actuator faults using bank of observer and unknown input observers (UIO). Full order observers, reduced order observers, unknown input observers and Kalman Filter are widely used in state estimations [1]. After the estimation of states, fault detection and isolation can be provided by conducting ...

Fault-tolerant Flight Control System Using Model Predictive Control

This work presents a fault-tolerant flight control system using model predictive control (MPC). The proposed technique, named feasible target-tracking MPC, filters the reference demand to guarantee feasibility of the constrained optimization. This architecture is also capable of redistributing, in a stable manner, the control efforts among healthy actuators, respecting their limitations. A traj...

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...

Dependability of Distributed Control System Fault Tolerant Units

We investigate two types of fault tolerant units (FTU’s) suitable for dependable distributed control systems and numerically evaluate their reliability and mean time to failure (MTTF). A simple simulation-based methodology to numerically evaluate dependability functions of a wide variety of fault tolerant units is presented. The method is based on simulation of stochastic Petri Nets. A set of 1...
