Sliding mode control for high-precision motion of a piezostage [PDF]

, 2007
In this paper, control of piezostage using sliding mode control (SMC) method is presented. Due to the fast dynamics of piezostage and since high accuracy is required the special attention is paid to avoid chattering.

Robust Super-Twisting Sliding Mode Backstepping Control Blended with Tracking Differentiator and Nonlinear Disturbance Observer for an Unknown UAV System

Applied Sciences, 2022
In this study, we examined the robust super-twisting sliding mode backstepping control (SBSC) method, which employed a tracking differentiator and nonlinear disturbance observer for a hexacopter unmanned aerial vehicle (UAV) system.

LMI-Based Reset Unknown Input Observer for State Estimation of Linear Uncertain Systems [PDF]

, 2018
This paper proposes a novel kind of Unknown Input Observer (UIO) called Reset Unknown Input Observer (R-UIO) for state estimation of linear systems in the presence of disturbance using Linear Matrix Inequality (LMI) techniques.

Upacicalcet: A Novel Intravenous Calcimimetic Agent for Patients Undergoing Hemodialysis With Secondary Hyperparathyroidism

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Secondary hyperparathyroidism (SHPT) is a common complication in patients receiving maintenance dialysis, driven by calcium and phosphate metabolism disturbances. Calcimimetics are central to the management of SHPT by enhancing calcium‐sensing receptor sensitivity and reducing parathyroid hormone secretion.

Minimum-order exosystem-model-based disturbance observer and the relation among the disturbance observers

SICE Journal of Control, Measurement, and System Integration
The authors aim to show the relation among the disturbance observers. This paper considers disturbance observers, which are constructed to estimate the steady disturbance affecting the outputs of the plants with the same inputs and outputs.
