Magneto-optical imaging of voltage-controlled magnetization reorientation
, 2011 We study the validity and limitations of a macrospin model to describe the voltage-controlled manipulation of ferromagnetic magnetization in nickel thin film/piezoelectric actuator hybrid structures.

Advanced Functional Materials, EarlyView.Light reflectance increases along incidence angle and transmittance significantly drops around 90‐degree incidence angle. Here, we report two‐photon laser printed micro mirrors that redirect the skimming light beam into normal light absorption. Using this technique, light‐driven micro walkers and grippers are demonstrated by using grazing incidence ...

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).

Advanced Functional Materials, EarlyView.Tailored thermo‐mechanical properties of shape memory polymer composites enable large reversible deformation as well as high actuation speed. Moreover, a structural design with curvature in the transverse direction achieves sub‐second actuation on heating and a larger recovery ratio on cooling. Finally, these newly developed smart two‐way actuators can

Influence of the core saturation on the dynamic performance of the magnetostrictive actuator
Archives of Electrical Engineering, 2017 The paper considers the influence of core saturation on the dynamics of magnetostrictive fast-acting actuator. The field-circuit mathematical model of the dynamic operation of the capacitor-actuator system is applied.

A virtual actuator approach for the secure control of networked LPV systems under pulse-width modulated DoS attacks [PDF]
, 2019 In this paper, we formulate and analyze the problem of secure control in the context of networked linear parameter varying (LPV) systems. We consider an energy-constrained, pulse-width modulated (PWM) jammer, which corrupts the control communication ...

Novel Functional Materials via 3D Printing by Vat Photopolymerization
Advanced Functional Materials, EarlyView.This Perspective systematically analyzes strategies for incorporating functionalities into 3D‐printed materials via Vat Photopolymerization (VP). It explores the spectrum of achievable functionalities in recently reported novel materials—such as conductive, energy‐storing, biodegradable, stimuli‐responsive, self‐healing, shape‐memory, biomaterials, and

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