Passive fault tolerant control of quadrotor UAV using a nonlinear PID

2015 IEEE International Conference on Robotics and Biomimetics (ROBIO), 2015
In 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), 2009
The 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), 2009
Many 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.

Active Fault-Tolerant Control of Quadrotor UAVs Based on Passive Controller Bank

2018
In 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

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.
