Integrated Fault Estimation and Fault-Tolerant Control for Drive-by-Wire Steering Systems in Four-Wheel Independent Drive Vehicles

Sensors
This study proposes an integrated fault estimation and fault-tolerant control strategy for actuators of four-wheel independently driven vehicles. Firstly, a modeling approach is developed by combining the vehicle dynamics model with the steering actuator

Actuator Fault Diagnosis with Robustness to Sensor Distortion

Journal of Control Science and Engineering, 2008
Actuator fault diagnosis is often studied under strong assumptions on available sensors. Typically, it is assumed that the sensors are either fault free or sufficiently redundant.

Delay-Dependent Fault-Tolerant Shape Control for Stochastic Distribution Systems

IEEE Access, 2018
A new adaptive delay-dependent fault-tolerant shape control strategy is proposed for the stochastic distribution system with time-delay, which can effectively make the output probability density function (PDF) track a given target distribution.

Adaptive fault-tolerant control based on boundary estimation for space robot under joint actuator faults and uncertain parameters

Defence Technology, 2019
Since the joint actuator of the space robot executes the control instructions frequently in the harsh space environment, it is prone to the partial loss of control effectiveness (PLCE) fault. An adaptive fault-tolerant control algorithm is designed for a
