Experimental investigation of a SMC high precision control [PDF]
, 2006 In this paper a discrete-time Sliding-Mode (SM) based controller for high accuracy position control is investigated. The controller is designed for a general SISO system with nonlinearity and external disturbance. It will be shown that application of the

Data-driven load disturbance rejection
, 2023 Data-driven direct methods are still growing in popularity almost three decades after they were introduced. These methods use data collected from the process to identify optimal controller's parameters with little knowledge about the process itself. However, most of those works focus on the problem of reference tracking, whereas many of the problems ...

Advanced Materials, EarlyView.Zonated osteochondral assembloid implants are engineered through scaffold‐free spatial assembly of induced pluripotent stem cell (iPSC)‐derived chondrocyte organoids and periosteum‐derived osteogenic organoids. Implanted into full‐thickness rat osteochondral defects, they promote hyaline‐like cartilage repair, support subchondral bone formation with ...

Nested Distributed Model Predictive Control [PDF]
, 2017 We propose a distributed model predictive control approach for linear time-invariant systems coupled via dynamics. The proposed approach uses the tube MPC concept for robustness to handle the disturbances induced by mutual interactions between subsystems;

Direct Adaptive Rejection of Persistent Disturbances
Journal of Mathematical Analysis and Applications, 2000 The paper deals with a system \( x'=Ax+Bu+Gu_d\), \(y= Cx\), where \(u_d\) is a persistent disturbance. It is assumed that the persistent disturbance has a finite representation \(u_d=a_1e_1f_1+\dots +a_le_lf_l\) with \(a_k\) constant scalars, \(e_k\) constant vectors, \(f_k\) functions with \(\|f_k\|=1\).

Light‐Programmable Interfaces: From Molecular Photoswitching to Adaptive Membrane Separations
Advanced Materials Interfaces, EarlyView.This review advances an interface‐centered framework for light‐responsive membranes, linking molecular photoswitches (azobenzene (AZO), spiropyran (SP), diarylethene (DAE), donor–acceptor Stenhouse adducts (DASA), photoacid) to integration strategies in polymeric, porous, self‐assembled, and mixed‐matrix systems.
