Persistent magnetic resonance imaging‐derived static anterior tibial translation after anterior cruciate ligament reconstruction is associated with elevated cartilage T2 relaxation times but not serum biomarkers

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Persistent, static anterior tibial translation (sATT) alterations following anterior cruciate ligament reconstruction (ACLR) may influence cartilage health. T2 relaxation times and serum biomarkers of cartilage degradation/bone resorption provide insight into osteoarthritis development.

Decentralized robust load-frequency control: A PI-based approach [PDF]

, 2004
This paper addresses a robust control method to decentralized PI-based load-frequency control (LFC) synthesis in a multi-area power system. The LFC problem is reduced to a static output feedback H∞ control problem and then it is solved using a developed ...

Calculating the Interconnection Limit from a Comprehensive Voltage Evaluation for Distribution Systems with Large Distributed Energy Resources

IEEJ Transactions on Electrical and Electronic Engineering, EarlyView.
Japan is pursuing power source decarbonization and is thus reducing fuel‐based thermal power generation while promoting renewable energy resource use. Given the expected power fluctuations, this transition will require novel voltage management and control methods.

Robust load-frequency control design for time-delay power systems [PDF]

, 2005
This paper addresses a control strategy to design a PIbased load-frequency control (LFC) in face of communication delays. First the PI-based LFC design is transferred to a static output feedback (SOF) control design and then to obtain the optimal PI ...

Load–frequency control : a GA-based multi-agent reinforcement learning

, 2010
The load–frequency control (LFC) problem has been one of the major subjects in a power system. In\ud practice, LFC systems use proportional–integral (PI) controllers.

An Investigation of Coordinated Attack on Load Frequency Control

IEEE Access, 2018
In this paper, optimal attack schemes against load frequency control (LFC) are studied by considering coordinated attack. By attacking sensor measurement (load) simultaneously, the attacker disrupts the normal operation of LFC, thus causing excess system
