Almost Global Stabilization of Curvature-Nullifiable Mechanical Systems via Pure Mechanical Feedback

Applied Sciences
Mechanical control systems structure, derived from Euler–Lagrange dynamics, is directly tied to physically meaningful coordinates such as joint angles, positions, and velocities. This work investigates when a mechanical control system can be transformed,

Modelling and Simulation of LQR and LFSV Controllers in the Magnetic Levitation System (MLS)

Prospectiva, 2016
In this article a control analysis in state variables is presented, applied to the nonlinear Magnetic Levitation system (MLS), which consists in keeping objects suspended in the air without any mechanical contact through the interaction of magnetic force.

A QFT robust controller as a remedy for TRMS

Aviation, 2020
Control of a Twin Rotor Multi-input Multi-output System (TRMS) is not a simple work. Because it has complex nonlinear dynamics, cross-coupling, uncertainties, and instability.

Functionalizing Micro‐to‐Mesoscopic Electrode Architectures for Regulating Electron Transfer Behaviors in Electrocatalysis

Advanced Functional Materials, EarlyView.
A systematic review is conducted to assess the influence of electrode architecture across micro‐ to mesoscopic length scales on electron‐transfer pathways in electrocatalysis. We discuss the structure‐activity relationships in electrocatalytic applications, including resource recovery and environmental remediation, and provide cost‐effective, efficient

Intelligent Switching Control of Nonlinear Non-Minimum Phase Relative Degree two Systems [PDF]

, 2001
In this paper we extend earlier results on Invariance Control to the special class of nonlinear control input affine systems with relative degree two. A switching strategy for control parameters and an easy to calculate invariance region together form an
