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.

Fault Tolerant Control in a Semi-active Suspension [PDF]

IFAC Proceedings Volumes, 2012
Abstract A Fault Tolerant Control System (FTCS) in a Quarter of Vehicle (QoV) model is proposed. The control law is time-varying using a Linear Parameter-Varying (LPV) based controller, which includes two scheduling parameters. One parameter for monitoring the nonlinear behavior of the damper, and another for fault accommodation using a reference ...

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.
