Robust Mpc for Actuator–Fault Tolerance Using Set–Based Passive Fault Detection and Active Fault Isolation

International Journal of Applied Mathematics and Computer Science, 2017
In this paper, a fault-tolerant control (FTC) scheme is proposed for actuator faults, which is built upon tube-based model predictive control (MPC) as well as set-based fault detection and isolation (FDI).

Fault-Tolerant Vertical Load Redistribution of an Active Suspension Under Yaw-Rate and Roll-Rate Sensor Faults

Actuators
This study presents a fault-tolerant control framework for an EMA-based active suspension under yaw-rate and roll-rate sensor faults. Instead of deactivating active suspension functions in the presence of sensor failures, the proposed approach maintains ...
