Mitigation of cross-saturation effects in resonance-based sensorless switched reluctance drives [PDF]

, 2010
The stator and rotor yoke in a switched reluctance motor form magnetic circuit parts that are typically shared by different phases. If these parts saturate due to the excitation of one phase, this will lead to a change of the magnetic characteristics of ...

Disturbance‐Resilient Voltage/Power‐Quality Management for Islanded Inverters Using Self‐Tuning Type‐3 Fuzzy Controller

Energy Science &Engineering, EarlyView.
An adaptive fuzzy controller using an interval type‐3 fuzzy logic system replaces the SMC switching term to mitigate chattering while preserving global stability for islanded inverters. Simulations show lower THD, greater robustness to disturbances and parameter variations, and improved voltage‐tracking accuracy, with applicability to other uncertain ...

Optimal Control of VSC for STATCOM Applications [PDF]

IFAC Proceedings Volumes, 2012
Abstract In this work, a voltage source converter (VSC) is configured to perform STATCOM tasks and generate reactive power. An optimal H ∞ controller has been successfully implemented including an anti-windup compensator. Data from an experimental test bench is provided and compared with simulation results showing good accuracy level.

Effect of cow's milk protein allergy during infancy on eating behavior at 4 years of age: A cohort study

Journal of Pediatric Gastroenterology and Nutrition, EarlyView.
Abstract Objectives This study aimed to investigate the eating behaviors of preschool children who had been exposed to a restricted diet due to an oral food challenge‐confirmed diagnosis of cow's milk protein allergy (CMPA) during early infancy. Methods This prospective cohort study compared the eating behaviors of Brazilian children previously ...

Quantitative Analysis of Locus Coeruleus Neurons and Thalamic Noradrenergic Axons in a Progressive 1‐Methyl‐4‐phenyl‐1,2,3,6‐tetrahydropyridine Monkey Model of Parkinson's Disease

Movement Disorders, EarlyView.
Abstract Background Parkinson's disease is mainly characterized by dopaminergic neurodegeneration in the substantia nigra pars compacta (SNc) and α‐synuclein accumulation. The locus coeruleus (LC) is also affected in Parkinson's disease and linked to some nonmotor symptoms, but the extent and timing of its degeneration remain unclear.

Output Feedback‐Based Direct Yaw Control System and Finite‐Time Robust Dynamic Control Allocation for Unknown Road Conditions

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT This paper presents a three‐layer control architecture designed to enhance vehicle lateral stability under uncertain and varying road conditions. The system utilizes output‐feedback‐based finite‐time controllers to track the desired yaw rate and longitudinal slip in the upper and lower layers, respectively.
