Passive Actuators' Fault-Tolerant Control for Affine Nonlinear Systems

IEEE Transactions on Control Systems Technology, 2008
Abstract In this paper we consider the problem of passive fault tolerant control for nonlinear affine systems with actuators faults. We treat two types of faults; additive and loss of effectiveness faults. In each case we propose a Lyapunov-based feedback controller that ensures the local uniform asymptotic (exponential) stability of the faulty ...

A simultaneous stabilization approach to (passive) fault tolerant control

Proceedings of the 2004 American Control Conference, 2004
This paper discusses the problem of designing fault tolerant compensators that stabilize a given system both in the nominal situation, as well as in the situation where one of the sensors or one of the actuators has failed. It is shown that such compensators always exist, provided that the system is detectable from each output and that it is ...

Passive fault tolerant control strategy in controlled wind turbines

2016 3rd Conference on Control and Fault-Tolerant Systems (SysTol), 2016
In wind turbines (WTs), some faults can induce saturation of the control signal, and these saturation nonlinearities might lead to instability. Therefore, a robust system against saturation can better deal with faults. In this work, an avoid saturation strategy is proposed for the torque control of WTs.

Experimental passive fault tolerant control for gyroscope system

21st Mediterranean Conference on Control and Automation, 2013
This paper is dedicated to the passive fault tolerant control of moment gyroscope. Erroneous sensor reading and actuator faults reduce the performance and may even cause the instability. As a matter of fact, the control of the gyroscope system when these drawbacks are occurred often requires the fault tolerant control design.

Mixed passive / active strategy for fault tolerant control.

IFAC Proceedings Volumes, 2009
Abstract This paper presents a general frame in which the passive and active fault tolerant control strategies are mixed, by implementing several controllers, each dedicated to a subset of faults. The faults under consideration are associated with different hardware configurations, a problem setting that covers actuator outages, sensor losses, and ...

A hybrid active–passive fault‐tolerant control approach

Asia-Pacific Journal of Chemical Engineering, 2006
AbstractThis paper presents a hybrid active–passive approach to fault‐tolerant control (FTC). It combines the existing active fault‐tolerant control techniques with the newly developed passive decentralized unconditionally stabilizing (DUS) control.

Passive fault-tolerant flight controller design against actuator outages

Proceedings of 2014 IEEE Chinese Guidance, Navigation and Control Conference, 2014
A model to represent multiple actuator failure cases is developed by polytopic concept. The design of passive fault-tolerant control (FTC) with considerations of both normal and actuator failure cases is investigated, depending on the availability of actuator redundancies.
