Autor: Gustavo C. Costa, L. L. Pfitscher, Douglas de Matos Magnus, C.C. Scharlau

Publikováno v: Anais do Congresso Brasileiro de Automática 2020.

Este artigo apresenta uma nova abordagem para projeto integrado de controladores de inércia sintética e de velocidade para aerogeradores de velocidade variável por meio da técnica de inércia oculta. O diferencial do trabalho é o uso de controle

A novel approach for robust control design of hidden synthetic inertia for variable speed wind turbines

Autor: Guilherme M. Silva, Douglas de Matos Magnus, L. L. Pfitscher, C.C. Scharlau, Gustavo C. Costa

Publikováno v: Electric Power Systems Research. 196:107267

This work presents a novel design methodology for hidden synthetic inertia control of variable speed wind turbines that considers the compromise between grid frequency response and operating limits of the wind turbine states. Two state space design s

Acidity enhancement of niobia by sulfation: An experimental and DFT study

Autor: Célia Sousa, Angela Sanches Rocha, Priscila Tamiasso-Martinhon, Gustavo C. Costa, Alexandre B. Rocha

Publikováno v: Materials Chemistry and Physics. 186:138-145

Acidic solids are used as catalyst at several industrial processes and studies to improve their activities have been developed by different groups. One method well known is sulfating oxide to create new acid sites, but investigations about sulfated n

Do muscle strengthening exercises improve performance in the 6-minute walk test in postmenopausal women? O exercício de força muscular é eficiente para melhorar o desempenho no teste de caminhada de 6 minutos em mulheres pós-menopausais?

Autor: Júlia G. Reis, Gustavo C. Costa, André Schmidt, Cristine H. J. Ferreira, Daniela C. C. Abreu

Publikováno v: Brazilian Journal of Physical Therapy, Vol 16, Iss 3, Pp 236-240 (2012)

BACKGROUND: Walking speed seems to be related to aerobic capacity, lower limb strength, and functional mobility, however it is not clear whether there is a direct relationship between improvement in muscle strength and gait performance in early postm
