Non-affine Nonlinear Flight Control System Based on Robust Adaptive Fault-tolerant Control

Decentralized adaptive fuzzy fault-tolerant tracking control of large-scale nonlinear systems with actuator failures

This study is concerned with the problem of decentralized adaptive faulttolerant control for a class of large-scale non-affine and nonlinear systems with external disturbances and actuator failures including loss of effectiveness and bias. Based on fuzzy logic systems (FLSs) to approximate the appropriate nonlinear functions, a novel decentralized adaptive fuzzy fault-tolerant control scheme is...

Passivity-Based Stability Analysis and Robust Practical Stabilization of Nonlinear Affine Systems with Non-vanishing Perturbations

This paper presents some analyses about the robust practical stability of a class of nonlinear affine systems in the presence of non-vanishing perturbations based on the passivity concept. The given analyses confirm the robust passivity property of the perturbed nonlinear systems in a certain region. Moreover, robust control laws are designed to guarantee the practical stability of the perturbe...

Robust Fault-Tolerant Tracking Control Scheme for Nonlinear Nonaffine-in-control Systems Against Actuator Faults

In this paper a theoretical framework of robust fault-tolerant control (FTC) for a class of nonlinear nonaffine-in-control systems is developed. In the framework, an observer-like auxiliary system is designed via adaptive and sliding mode techniques, which is only required to ensure that the output of the auxiliary system asymptotic tracking plant output. Based on the auxiliary system, a reconf...

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

Optimal nonlinear control of flight faults in manned aircrafts in the presence of fault and failure of control actuato

Control actuators' faults are among the major reasons to lose aircraft control while flights. The plane dynamics is severely dependent upon faults and errors in flight control systems and if the reformed control order is not issued by the fault tolerant controller there would be unpleasant outcomes such as inconsistency and the reduction of system performance and some dreadful aerial accide...
