A nonlinear strategy to control unstable underactuated mechanical systems with underactuation > 1. Applications to control augmentations

, 2009
The essence of the complex dynamics originated by the interaction between the pilot-&-aircraft can be captured on labs, by means of unstable-underactuated mechanical systems.

A data-driven model predictive control approach toward feedback linearization of nonlinear mechanical systems [PDF]

, 2020
This paper presents a novel approach to linearize the input-output (IO) response of nonlinear mechanical systems by using model predictive control (MPC) with integral action and solving a one-step-ahead reference tracking problem.

Embedded Oriented Object Detection on MaixCAM Pro for Waste-Sorting Perception

Sensors
For sorting mechanisms that operate on a planar platform, the perception module may need to estimate object category, image-plane position, object extent and principal-axis orientation within the computing budget of a low-power device. This paper reports

Golgi enzymes are retrieved from the plasma membrane to the trans‐Golgi network

FEBS Letters, EarlyView.
Golgi enzymes are traditionally considered resident proteins retained within the Golgi apparatus. Here, we demonstrate that a subset transiently reaches the cell surface and is subsequently retrieved to the trans‐Golgi network via retrograde transport. Using a nanobody‐based toolkit, we uncover a dynamic trafficking cycle of several Golgi enzymes.

Analysis of Friction Compensation Effects in Controlled Mechanical Systems

, 2006
In this paper, the effects of friction compensation, including exact compensation, undercompensation and overcompensation, in PD controlled 1DOF mechanical systems are investigated.

High-performance regulator control for mechanical systems subjected to friction

, 2001
Several control strategies are compared with respect to their performance for regulator tasks on mechanical systems that exhibit friction. For this purpose a classic PID-controller combined with mass and frictional feedforward is compared to (i) a PID ...

Partial depletion of plasminogen activator inhibitor‐1 decreases subcutaneous fat cell hypertrophy and liver cholesterol in high‐fat‐fed female mice

FEBS Letters, EarlyView.
Obesity raises blood levels of PAI‐1, a protein linked to metabolic dysfunction‐associated steatotic liver disease in people with obesity. In female mice fed a high‐fat diet, partially lowering PAI‐1 led to smaller subcutaneous fat cells and lower liver cholesterol, without changing body weight or insulin sensitivity.

Control engineering : control system power and grounding better practice /

, 2004
Control system power and grounding is possibly the single most important element to ensure a control system doesn't experience unidentified 'gremlins' throughout its life.
