Optimizing stability bounds of finite-precision PID controller structures [PDF]

, 1999
The paper investigates a recently derived lower bound stability measure for sampled-data controller structures subject to finite-word-length (FWL) constraints. The optimal realization of the digital PID controller with FWL considerations is formulated as

Nanoparticle‐Mediated Bubble Suppression During Droplet Solidification for Mechanical Reinforcement

Advanced Science, EarlyView.
Nanoparticles mediate droplet solidification by raising nucleation temperature, refining dendrites, and slowing freezing‐front advance, thereby suppressing trapped air bubbles in droplet‐based 3D printing. This strategy reduces bubble volume fraction by ∼35% and increases compressive strength by up to 39%, offering a low‐cost route to stronger printed ...

RDA Recommendation on PID Kernel Information (draft)

, 2018
Global middleware infrastructure is insufficient for robust data identification, discovery, and use. While infrastructure is emerging within sub-ecosystems such as the DOI ecosystem of services purposed for data and literature objects (i.e., DataCite ...

Influence of Top Electrode Metal on Resistive Switching in Multilayer MOCVD MoS2 Memristors

Advanced Electronic Materials, EarlyView.
MoS2 memristors typically use evaporated noble metal electrodes. This study compares Pd, Ni, and Al electrodes and sputtered versus evaporated deposition. Pd is passive, while Ni damages MoS2, yielding poor switching. Sputtered Al enables reproducible ECM‐type switching with 95% yield, whereas evaporated Al forms an interfacial oxide that suppresses ...

Synthesis of FEEDFORWARD COMPENSATOR in the combined SYSTEM OF AUTOMATIC control WITH PID-REGULATION ON the main CHANNEL circuit

Доклады Белорусского государственного университета информатики и радиоэлектроники, 2019
An automatic control system for the 1st order aperiodic object is suggested. The structural scheme includes main control circuit with a PID-regulator in it and a disturbance compensation circuit realized by two additional PID-regulators.

A Study on Automatic Tuning of Ship's PID Regulators

Journal of the Society of Naval Architects of Japan, 1996
The classical PID control law is still used for many marine control systems. Gain tuning in the controller is, however, a formidable task for mariners. This paper provides a simple and a safe automatic P, I, D gains tuning method using relay control, for typical marine controllers with PID control law.In this method, a limit cycle with small amplitude ...

A Computational Approach for Biomimetic Design of Liver‐On‐A‐Chip

Advanced Intelligent Discovery, EarlyView.
A biomimetic liver‐on‐a‐chip with antiparallel perfusion was designed using COMSOL‐guided simulation to replicate hepatic acinus transport. Full‐scale modelling revealed diffusion‐dominated, length‐dependent nutrient gradients and low‐shear conditions.

Self‐Driving Laboratory Optimizes the Lower Critical Solution Temperature of Thermoresponsive Polymers

Advanced Intelligent Discovery, EarlyView.
A low‐cost, self‐driving laboratory is developed to democratize autonomous materials discovery. Using this "frugal twin" hardware architecture with Bayesian optimization, the platform rapidly converges to target lower critical solution temperature (LCST) values while self‐correcting from off‐target experiments, demonstrating an accessible route to data‐
