Closed Loop Capacitive Accelerometer Model using Simple Regression Test for Linearity

Advances in Science, Technology and Engineering Systems Journal, Volume 6, Issue 2, Page # 1038–1045, 2021; DOI: 10.25046/aj0602118
Abstract:

This article extends novelty of modeling capacitive accelerometer with PID controller to provide PI controller for better tuning and statistical test to determine the linear validation characteristics of closed capacitive accelerometer. Capacitive accelerometer is a sensor which uses the dynamic law of physics model Position-Velocity-Accelerator (PVA) by the movement of an electrode coupled to mass…

System-Level Test Case Design for Field Reliability Alignment in Complex Products

Advances in Science, Technology and Engineering Systems Journal, Volume 10, Issue 6, Page # 55–64, 2025; DOI: 10.25046/aj100605
Abstract:

Achieving targeted reliability for complex products in real-world field environments remains a persistent challenge, even when laboratory validation suggests high performance. A significant reliability gap often emerges during the initial deployment phase, typically within the first one to five years where field failure rates can be up to twice those predicted in controlled settings. Compounding…

Open Energy Distribution System-Based on Photo-voltaic with Interconnected- Modified DC-Nanogrids

Advances in Science, Technology and Engineering Systems Journal, Volume 6, Issue 1, Page # 982–988, 2021; DOI: 10.25046/aj0601108
Abstract:

This manuscript exhibits a perfect design for a flexible number of modified DC nanogrids within an open energy distribution network (OEDN) that interconnected via a DC bus. Each modified nanogrid implies a single-input multi-output switched boost inverter (SIMO-SBI). The DC-output for each inverter is robustly controlled to keep the DC-bus interconnected voltage constant. The proposed…

A Comparison of MIMO Tuning Controller Techniques Applied to Steam Generator

Advances in Science, Technology and Engineering Systems Journal, Volume 3, Issue 3, Page # 7–14, 2018; DOI: 10.25046/aj030302
Abstract:

This work presents a comparison between controller tuning methods for a multivariable steam generator. Controller tuning has a remarkable impact on closed loop performance. Methods selected were Single-Loop Tuning (SLT), Biggest Log Modulus Tuning (BLT), Sequential Return- Difference (SRD) and Structured H(inf) Synthesis (S-H(inf)). Method assessment takes into account set-point tracking, disturbance rejection, tuning effort and…

Feedback device of temperature sensation for a myoelectric prosthetic hand

Advances in Science, Technology and Engineering Systems Journal, Volume 2, Issue 3, Page # 41–47, 2017; DOI: 10.25046/aj020307
Abstract:

In this study, a control system of a feedback device of temperature sensation for myoelectric prosthetic hand users was improved. The device is mounted on a user’s upper arm in contact with the skin, and transfers the temperature sensation in the upper arm corresponding to the temperature detected by the temperature sensor at the fingertip…

Optimal Discrete-time Sliding Mode Control for Nonlinear Systems Subject to Input Constraints

Advances in Science, Technology and Engineering Systems Journal, Volume 4, Issue 4, Page # 141–146, 2019; DOI: 10.25046/aj040417
Abstract:

In this paper, an optimal discrete-time sliding mode control is proposed for single-input single-output nonlinear systems with input constraints. The sliding surface is designed on the basis of particle swarm optimization algorithm in order to optimize the system response characteristics while ensuring the follow-up of reference model in presence of constraints. Moreover, the controller is…
