Fault-tolerant PID controllers using a passive robust fault diagnosis approach
Control Engineering Practice, 2000Abstract Automatic controlled systems are susceptible to faults. Faults can be amplified by closed loop control systems, and they can cause a malfunction of the loop. The closed loop may alternatively hide a fault from being observed until the plant eventually reaches a state in which loop failure is inevitable.

Transactions of the Institute of Measurement and Control
In this paper, the fault-tolerant control (FTC) problem of fixed-wing unmanned aerial vehicle (UAV) with control surface structural damage is studied. An active-passive combined FTC algorithm based on sliding mode and adaptive control is proposed. Considering that the UAV is required to be instantaneously stable in the initial stage of the fault, a one-

Active Fault-Tolerant Control of Quadrotor UAVs Based on Passive Controller Bank
2018In this paper, an Active Fault Tolerant Control (AFTC) scheme for quadrotor UAVs suffering from actuator loss of effectiveness fault is presented. The AFTC is based on Passive Fault Tolerant Controller (PFTC) bank that contains a group of Sliding Mode Controllers, each one tuned to give the best performance for a specific fault.

Passive Fault Tolerant Control of Induction Motors Using Nonlinear Block Control
2017This 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.
