Conference Proceeding
La Spada, L., & Hao, Y. (2015)
Surface wave cloaking using transformation optics. In 2015 1st URSI Atlantic Radio Science Conference (URSI AT-RASC)doi:10.1109/ursi-at-rasc.2015.7302892
Recently, there has been an increasing interest in the study of manipulating surface waves from microwave to optical frequencies [1, 2], especially for the design of conformal...

Electromagnetic modeling of metamaterial-based sensors

Conference Proceeding
Spada, L. L. (2015)
Electromagnetic modeling of metamaterial-based sensors. doi:10.1109/imws-bio.2014.7032448
In this paper metamaterial-based sensors electromagnetic modeling is presented. In particular, the interaction between the electromagnetic waves and such structures is analyti...

Robust chattering-free (higher order) sliding mode control for a vector-controlled induction machine

Conference Proceeding
Goh, K., Dunnigan, M., & Williams, B. (2005)
Robust chattering-free (higher order) sliding mode control for a vector-controlled induction machine. In 2004 5th Asian Control Conference (IEEE Cat. No.04EX904)
The chattering behaviour that is inherent in standard sliding mode control is often an obstacle for practical application if neglected. In this paper, special attention is giv...

Sliding mode position control of a vector-controlled induction machine with nonlinear load dynamics

Conference Proceeding
Goh, K., Dunnigan, M., & Williams, B. (2004)
Sliding mode position control of a vector-controlled induction machine with nonlinear load dynamics. In Second International Conference on Power Electronics, Machines and Drives (PEMD 2004)https://doi.org/10.1049/cp%3A20040264
In this paper, a solution to the position control problem for a vector controlled induction machine in the presence of nonlinear load friction, is proposed. A sliding mode (SM...
