Robust Quasi–LPV Model Reference FTC of a Quadrotor Uav Subject to Actuator Faults

International Journal of Applied Mathematics and Computer Science, 2015
A solution for fault tolerant control (FTC) of a quadrotor unmanned aerial vehicle (UAV) is proposed. It relies on model reference-based control, where a reference model generates the desired trajectory.

Multiferroic‐Centric Materials and Systems Engineering for Battery Applications: An Insight Into Mechanisms, Strategies, and Characterizations

Advanced Science, EarlyView.
Multiferroic order parameters – polarization, magnetization, and ferroelastic strain – are positioned as dynamic design variables for batteries. Their mechanistic roles, practical tuning through fabrication and external fields, and ferroic‐resolved characterization routes are unified into a closed‐loop framework, revealing how coupled ferroic responses

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 ...
