Robust Control of A Class of Nonlinear Uncertain Systems Fault Tolerance Against Sensor Failures and Subsequent Self Recovery

In this paper, the problem of devising a fault-tolerant robust control for a class of nonlinear uncertain systems is investigated. Possible failures of the sensors measuring the state variables are considered, and robust measures are developed to identify the stability-vulnerable failures. Based on evaluation of the robust measures, a fault-tolerant robust control will switch itself among sever...

A Robust Adaptive Observer-Based Time Varying Fault Estimation

This paper presents a new observer design methodology for a time varying actuator fault estimation. A new linear matrix inequality (LMI) design algorithm is developed to tackle the limitations (e.g. equality constraint and robustness problems) of the well known so called fast adaptive fault estimation observer (FAFE). The FAFE is capable of estimating a wide range of time-varying actuator fault...

Incremental Nonlinear Adaptive Flight Control with Online System Identification

Research into previous flight accidents and investigations of the fault-tolerant flight control (FTFC) strategies used suggest that an aircraft, under many post-failure circumstances, can still achieve a certain level of flight performance using the remaining valid control effectors. However, the control authority or the safe flight envelope of the aircraft will inevitably shrink due to structu...

Robust fault-tolerant self-recovering control of nonlinear uncertain systems

In this paper, the problem of devising a fault-tolerant robust control for a class of nonlinear uncertain systems is investigated. Possible failures of the sensor measuring the state variables are considered, and a robust measure is developed to identify the stabilityand performance-vulnerable failures. Based on evaluation of the robust measure, a fault-tolerant robust control will switch itsel...
