Control of Fully Actuated Unmanned Aerial Vehicles with Actuator Saturation

IFAC-PapersOnLine, 2017
Abstract A natural way to control fully actuated UAVs is the use of feedback linearization. Indeed, given a sufficiently good knowledge of UAV mechanical properties, the resulting closed-loop system is linear and well-suited for further developments (e.g. impedance-based control for physical interactions).

Energy‐Efficient Bulk Photoalignment of Main‐Chain Liquid Crystalline Polymers Enabled by In Situ Monitoring

Advanced Functional Materials, EarlyView.
In situ monitoring of bulk photoalignment reveals how molecular weight, azobenzene content, cooling rate, and thickness govern ordering in main‐chain liquid crystalline polymers. Optimized copolymers exceed conventional thickness limits, maintaining stable alignment up to 130 µm with high energy efficiency and reversible optical patterning.

Actuator-Aware Evaluation of MPC and Classical Controllers for Automated Insulin Delivery

Actuators
Automated insulin delivery (AID) systems depend on their actuators’ behavior since saturation limits, rate constraints, and hardware degradation directly affect the stability and safety of glycemic regulation.

Robust Non-Fragile Control of Positive Semi-Markovian Jump Systems With Actuator Saturation

IEEE Access, 2019
This paper is concerned with the non-fragile control problem of the positive semi-Markovian jump systems with actuator saturation. For the semi-Markovian process, a class of non-exponential distributions is considered as the probability distribution of ...
