Adaptive fault tolerant control for active suspension
2016 IEEE First International Conference on Control, Measurement and Instrumentation (CMI), 2016This paper deals an adaptive fault tolerant control for active suspension in the presence of actuator saturation. An adaptive state-feedback controller is designed to tackle the issue of actuator fault. A Disturbance observer is utilized to observe the lumped disturbance.

Two-level Active Fault Tolerant Control approach
Eighth International Multi-Conference on Systems, Signals & Devices, 2011In this paper, a two-level reconfiguration action is used to design an Active Fault Tolerant Control (AFTC) system. The first level of the procedure is triggered when the impact of the fault on the system performance is limited. The reconfigurable controller is updated by the new post-fault system model.

Fault tolerant control of active magnetic bearings
IEEE International Symposium on Industrial Electronics. Proceedings. ISIE'98 (Cat. No.98TH8357), 2002A nonlinear model of a Rolls-Royce turbomachine's rotor supported by active magnetic bearings (AMBs) is presented. The model has the capability to model magnetic bearing systems of a variety of different configurations. A multiobjective genetic algorithm (MOGA) is used to design PID controllers for the AMB system with five different bearing ...

Safer Batteries via Active Fault Tolerant Control
2019 American Control Conference (ACC), 2019Safety remains a critical technological barrier for Lithium-ion batteries. Besides safer battery materials, intelligent battery management can be the key to safer batteries. Motivated by this scenario, we propose an active fault tolerant control scheme which can potentially improve battery safety.

Implementation of Intelligent Active Fault Tolerant Control System
2007This paper addresses implementation of intelligent active fault tolerant control for experiment set which is a FODPT (First Order Plus Dead Time) system. Temperature control has been done using fuzzy logic controller (FLC). Faults often cause undesired reactions, so to keep the system stable and acceptable control performance is an important problem ...

Fault-tolerant model predictive control with active fault isolation
2013 Conference on Control and Fault-Tolerant Systems (SysTol), 2013A robust control method is presented for linear systems subject to input and state constraints, bounded disturbances and measurement noise, and discrete faults in sensors, actuators, and system dynamics. The approach uses set-based fault detection and isolation techniques to coordinate switching between controllers designed for each fault scenario.

Active Actuator Fault Tolerant Control Design for Polytopic LPV Systems
IFAC Proceedings Volumes, 2006In this paper, an Active Fault Tolerant Control (FTC) strategy is developed for polytopic Linear Parameter Varying (LPV) systems. The main contribution concerns the design of a linear Output Feedback dedicated to polytopic LPV systems. Based on an available Fault Detection, Isolation (FDI) scheme, the controllers redesign is performed on-line trough ...

An Active Fault-Tolerant Flight Control Strategy
2013This chapter deals with the next step following the design of an FDD system, i.e. appropriate recovery strategies, based on all available actuator/sensor/communication resources. An active fault tolerant flight control strategy based on H ∞ design tools is presented.

Active Fault-Tolerant Control: Current and Past
2017This chapter reviews the current and past status of the progress made in the area of FTC research. Most of the FTC techniques depends on the type of fault occurred into the system, where the FD plays a significant role. So, the chapter starts with classifying the types of faults followed by the discussion on fault diagnosis and the analysis of various ...

A hybrid active–passive fault‐tolerant control approach
Asia-Pacific Journal of Chemical Engineering, 2006AbstractThis 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.
