Sensor-fault tolerance using robust MPC with set-based state estimation and active fault isolation [PDF]
, 2014 In this paper, a sensor fault-tolerant control (FTC) scheme using robust model predictive control (MPC) and set theoretic fault detection and isolation (FDI) is proposed.

Robust fault tolerant control framework using uncertain Takagi-Sugeno fuzzy models [PDF]
, 2014 This chapter is concerned with the introduction of a fault tolerant control (FTC) framework using uncertain Takagi-Sugeno (FS) fuzzy models. Depending on how much information is available about the fault, the framework gives rise to passive FTC, active

Observer-Based Active Fault-Tolerant Control of an Asymmetric Twin Wind Turbine
Information, 2022 This paper deals with the design of an active fault-tolerant control based on observers for a twin wind turbine, consisting of two wind turbines mounted on the same tower. We consider an asymmetric conditions case, when only one turbine is affected by an

Active Fault Tolerant Control for Switched Systems with Time Delay [PDF]
International Journal of Adaptive Control and Signal Processing, 2011 AbstractThis paper focuses on the problem of active fault‐tolerant control for switched systems with time delay. By utilizing the fault diagnosis observer, an adaptive fault estimate algorithm is proposed, which can estimate the fault signal fast and exactly.

A Survey on Active Fault-Tolerant Control Systems [PDF]
Electronics, 2020 Faults and failures in the system components are two main reasons for the instability and the degradation in control performance. In recent decades, fault-tolerant control (FTC) approaches have been introduced to improve the resiliency of control systems against faults and failures.
