Design of a Variable Reactor for Load Balancing and Harmonics Elimination

Dalvand Hedayatollah; Su Steven; Ha Quang (University of New South Wales, 2008)

This paper presents the design of a variable inductor with a rotational magnetic core whose position is controlled in a closed-loop system. This magnetic structure facilitates the impedance changes which may be used for ...
Design of second-order sliding mode controllers for MR damper-embedded smart structures

Dalvand Hedayatollah; Nguyen Hung; Ha Quang (IAARC-University of Texas at Austin, 2009)

Design of a current controlled system for MR damper-embedded civil structures
A New Hybrid Filter for Power Quality Improvement in Unbalanced Load Conditions

Dalvand Hedayatollah; Nguyen Minh Tam; Kwok Ngai Ming; Ha Quang (IEEE, 2008)

This paper presents the design of a new hybrid filter for quality improvement of power systems in unbalanced conditions. This filter includes a variable passive filter in parallel with an active filter. The passive part ...
Seismic responses of civil structures under magnetorheological device direct control

Nguyen Minh Tam; Dalvand Hedayatollah; Yu Ying Hao; Ha Quang (Vilnius Gediminas Technical University, 2008)

This paper presents an efficient control strategy for magnetorheological (MR) dampers embedded in building structures to mitigate quake-induced vibrations. In this work, MR dampers are used as semi-active devices, taking ...
