Linear and Sliding-Mode Control Design for Matrix Converter-Based Unified Power Flow Controllers

Monteiro, J.; Silva, J. F.; Pinto, S. F.; Palma, J. (IEEE, 2014-07)

This paper presents the design and compares the performance of linear, decoupled and direct power controllers for three-phase matrix converters operating as Unified Power Flow Controllers (lIPFC). A simplified steady-state ...
Medição não-intrusiva da densidade superficial de depósitos de sedimentos em camada fina

Coelho, G.; Palma, J.; Alves, E. (SPMet - Sociedade Portuguesa de Metrologia, 2014-01)

O processo de medição de espessuras e de densidades superficiais de sedimentos depositados em modelos físicos tem sido motivo de investigação, conhecendo-se alguns métodos para o efeito, mas todos eles exibindo limitações ...
Predictive Control for Earthquake Response Mitigation of Building With Semi-Active Fluid Dampers

Oliveira, F. S. B. F.; Gil de Morais, P.; Suleman, A. (2013-06)

ln this paper a predictive control strategy in conjunction with sem i-active control algorithms are proposed for damping control of base isolation systems employing semi-active fluid dampers when subjected to earthquakes. ...
