Passive Fault Tolerant Control of Induction Motors Using Nonlinear Block Control
, 2017 This paper studies passive fault tolerant control (PFTC) of three phase induction motors (IMs). First, a nonlinear block control (NBC) transformation is applied to handle nonlinearities of motor faulty model. Afterwards, a fault tolerant speed controller is developed based on sliding mode control (SMC) technique with linear sliding surface.

Passive Fault-Tolerant Control of a Fixed-Wing UAV Based on Model-Free Control
2021 5th International Conference on Control and Fault-Tolerant Systems (SysTol), 2021Fixed-wing UAVs show a high interest and high challenges in control, fault diagnostic, and fault-tolerant control. Accurate models of highly coupled nonlinear systems as the Fixed-Wing UAV are complex and time consuming. A need to find a control architecture independent of the model, suitable for nonlinear systems and can reject disturbances is highly ...

Passive fault tolerant control strategy in controlled wind turbines
2016 3rd Conference on Control and Fault-Tolerant Systems (SysTol), 2016In 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.

Mixed passive / active strategy for fault tolerant control.
IFAC Proceedings Volumes, 2009Abstract 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 ...

Passive fault tolerant control of quadrotor UAV using a nonlinear PID
2015 IEEE International Conference on Robotics and Biomimetics (ROBIO), 2015In this paper a passive fault tolerant controller based on nonlinear PID backstepping is proposed for a quadrotor unmanned aerial vehicle. The proposed approach is able to ensure robustness and maintain performance in presence of both actuators faults and parameters changes.

Active versus passive fault tolerant control of a High Redundancy Actuator
2009 European Control Conference (ECC), 2009The High Redundancy Actuator (HRA project investigates the use of large numbers of small actuation elements to achieve fault tolerance. The large number of components involved poses a unique challenge from a control perspective. This paper presents the two main options to control the HRA: using robust control (passive fault tolerance), and ...

Passive/active fault tolerant control for LTI systems with actuator outages
2009 European Control Conference (ECC), 2009Many fault tolerant control applications consider a set of faults that is known in advance. Passive and active fault tolerance schemes aim at guaranteeing stability and performances for the whole set, differing by the level of simplicity and performance they allow.

Passive supervisor for railway fault-tolerant Ethernet networked control systems
ETFA2011, 2011In this study, OPNET simulations are run to study the performance of a single Gigabit Ethernet two-wagon train control network. The network carries both control and entertainment loads. Each wagon has two servers; a Controller to carry the control load and an Entertainment Server to carry the entertainment load.

Passive Fault Tolerance for a Magnetic Bearing Under PID Control
Volume 4: Manufacturing Materials and Metallurgy; Ceramics; Structures and Dynamics; Controls, Diagnostics and Instrumentation; Education; IGTI Scholar Award, 2001NASA Glenn Research Center (GRC) has developed a Fault-Tolerant Magnetic Bearing Suspension rig to enhance the safety of the bearing system for multiple component failures. A simple proportional-integral-derivative (PID) controller with no fault detection mechanisms was tested in a passive way where the initial bias current and control gains for all ...
