Experimental analysis of active-passive vibration control using viscoelastic materials and extension and shear piezoelectric actuators
(SAGE PUBLICATIONS LTD, 2011)
Hybrid active-passive damping treatments combine the reliability, low cost and robustness of viscoelastic damping treatments and the high-performance, modal selective and adaptive piezoelectric active control. Numerous ...
On the assumed inherent stability of semi-active control systems
(Elsevier, 2018-03)
Vibration control systems are usually classified into: passive, active and semi-active. Semi-active control systems are based on formerly passive mechanical devices, such as springs and dampers, whose characteristics are ...
RLC passive damped LCL single-phase voltage source inverter with capability to operate in grid-connected and islanded modes: design and control strategy
(2020-01-01)
A design procedure for an RLC damping branch applied at a voltage source inverter followed by an LCL output filter is carried out in this paper. The main purpose of the proposed methodology is to allow the system to operate ...
Implementation of a Power Hardware In-The-Loop Platform Using the Damping Impedance Method
(IEEE, 2020)
This paper presents the practical implementation of a PHIL simulation platform using the damping impedance method. To be successful this requires the identification of the impedance of the hardware under test. We use an ...
Application of the modified IDA-PBC for shunt active power filters control
(John Wiley & Sons Ltd, 2016-09)
The design of a passivity-based nonlinear controller for a shunt active power filter to be used for the compensation of harmonic currents consumed by nonlinear loads is presented in this paper. The main objective of designed ...
Controle robusto de inversores VSI com filtro LCL aplicados a geração distribuída, com controle da injeção de potências ativa e reativa na rede de distribuição em baixa tensão e capacidade de operação ilhada em ambiente de microrredes
