Robust Position Control of an Electro‐Hydraulic Actuator via Metaheuristic Optimization of a Fractional‐Order PID Controller

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT In this study, a robust position control strategy is presented for a two‐stage electro‐hydraulic actuator system using a fractional‐order proportional–integral–derivative (FOPID) controller tuned by Kirchhoff's law algorithm (KLA). Electro‐hydraulic systems exhibit strong nonlinearities, parameter uncertainties, and external disturbances ...

Trajectory Planning of a 6D Robot based on Meta Heuristic Algorithms

MATEC Web of Conferences, 2018
In this work, several established meta-heuristics (MHs) were employed for solving 6-DOF robot trajectory planning. A fourth order polynomial function is used to represent a motion path of the robot from initial to final points while an optimisation ...

Physics‐Informed Neural Networks for Battery Degradation Prediction Under Random Walk Operations

Quality and Reliability Engineering International, EarlyView.
ABSTRACT This study addresses the challenge of predicting the state of health (SoH) and capacity degradation in Battery Energy Storage Systems (BESS) under highly variable conditions induced by frequent control adjustments. In environments where random walk behavior prevails due to stochastic control commands, conventional estimation methods often ...

Competition and cooperation in evading threat meta-heuristic algorithm

Mathematics and Computational Sciences
This work introduces an innovative heuristic algorithm named "Competition and Collaboration in Evading Threat (CCET)". Inspired by the escape behavior of animals such as deer, buffalo, sheep, etc., from predators like lions, leopards, tigers, etc., and also drawing parallels with soldiers evading attacks in war zones involving missiles, cannons, tanks,

Tourism as a Catalyst for Blue Carbon Restoration and Conservation: Pathways, Gaps, and Opportunities

Sustainable Development, EarlyView.
ABSTRACT Tourism is a major driver of coastal economies worldwide, yet it is also a growing source of pressure on blue carbon ecosystems (BCEs) such as mangroves, seagrasses, and salt marshes. Nowadays, tourism‐led conservation/restoration is increasingly promoted under the banner of regenerative tourism, but how these projects are motivated ...

Unravelling Cascading Phenomena in Sociotechnical Systems: A Systematic Review and Modelling Framework

Systems Research and Behavioral Science, EarlyView.
ABSTRACT This article investigates the characterization of cascading phenomena within sociotechnical systems through a systematic review and the development of a conceptual modelling framework. Cascading phenomena, often described using terms such as ripple effect, domino effect, cascading failure, risk propagation and cascading effect, capture the far‐

A Novel Approach to Energy Management in Electric Steelworks

steel research international, EarlyView.
Feed‐forward neural networks are exploited to estimate electric energy consumptions of the electric arc furnace and ladle furnace processes. The models are used to optimize production schedule so that more energy intensive grades are produced when the cost of energy is lower.
