Reset Control for Vibration Disturbance Rejection

IFAC-PapersOnLine, 2019
The high tech industry which requires fast stable motion with nanometer precision continues to mainly use PID which is limited by fundamental linear control limitations. Floor vibrations as disturbance significantly affect performance and their rejection is particularly affected by these limitations.

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 ...

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 \(\|f_k\|=1\).

Probing Cellular Activity Via Charge‐Sensitive Quantum Nanoprobes

Advanced Materials, EarlyView.
A new quantum sensing modality detects shifts in zero‐field splitting caused by charge rearrangement with diamond nanocrystals in response to cellular activity. These electric‐field‐driven effects provide an alternative to temperature‐based interpretations, enabling real‐time, single‐cell readout of inflammation.
