Journal ArticleDOI
Parametric analysis of a sliding-mode controller to suppress drill-string stick-slip vibration
TL;DR: It is shown that though the proposed controller works robustly across a wide range of parameters, in the absence of delay, it fails in the presence of a delay, thereby limiting its practical application.
Journal ArticleDOI
Influence of the Sub-Peak of Secondary Surface Plasmon Resonance Onto the Sensing Performance of a D-Shaped Photonic Crystal Fibre Sensor

TL;DR: In this article, a fabricable 6-fold D-shaped photonic crystal fiber sensor based on the surface plasmon resonance (SPR) was investigated in detail, and the sensitivity of the proposed sensor was reduced from 1.33 − 1.41 to 1.45 at the cost of a reduced maximum sensitivity from 7900 nm/RIU to 5300 nm /RIU.
Journal ArticleDOI
Optimal Integral Force Feedback and Structured PI Tracking Control: Application for High Speed Confocal Microscopy.
TL;DR: In this paper, an improvement to Integral Force Feedback (IFF) damping control is proposed, which allows any arbitrary damping ratio to be achieved for a system by introducing a new feed-through term in the system.
Proceedings ArticleDOI
A hybrid control strategy for vibration damping and precise tip-positioning of a single-link flexible manipulator
TL;DR: In this article, the authors proposed a new control approach for a single-link flexible manipulator based on the Integral Resonant Control (IRC) scheme, which is a high performance controller design methodology for flexible structures with collocated actuator-sensor pairs.
Journal ArticleDOI
Butterworth Pattern-based Simultaneous Damping and Tracking Controller Designs for Nanopositioning Systems
TL;DR: In this paper, the authors presented a method for obtaining a closed-loop Butterworth filter pattern using common control schemes for positioning applications, i.e. Integral Resonant Control (IRC), Integral Force Feedback (IFF), Positive Position Feedback (PPF), and Positive Velocity and Position Feedback(PVPF).
