Sliding Vector Fields via Slow-Fast Systems
(Belgian Mathematical Soc Triomphe, 2008-01-01)
This paper concerns differential equation systems on R(n) with discontinuous right-hand sides. We deal with non-smooth vector fields in R(n) having a codimension-one submanifold M as its discontinuity set. After a ...
Sliding vector fields via slow-fast systems

Switching frequency reduction technique for DSVM-based predictive torque control of induction motor
(Institution of Engineering and Technology, 2020-08)
This study proposes a new strategy to decrease the switching frequency of the predictive torque control-discrete space vector modulation (PTC-DSVM) method, which is a combination of the PTC scheme and the DSVM. The principle ...
Resonant (P+RES) controller applied to voltage source inverter with minimum DC link capacitor
(2011-12-28)
Voltage source inverters use large electrolytic capacitors in order to decouple the energy between the utility and the load, keeping the DC link voltage constant. Decreasing the capacitance reduces the distortion in the ...

Solucao de sistemas lineares com matrizes e vetores esparsos em computadores vetoriais
(1997-09-01)
This paper presents a methodology for solving a set of linear sparse equations on vector computers. The new methodology is able to exploit the matrix and vector sparsities. The implementation was made on a CRAY Y-MP 2E/232 ...

On the dimension of permutation vector spaces
(Universidade Federal de Minas GeraisBrasilICX - DEPARTAMENTO DE MATEMÁTICAUFMG, 2019)
Seja K um campo que admite uma extensão de Galois cíclica de grau n≥2. O grupo simétrico Sn atua em Kn por permutação de coordenadas. Dado um subgrupo G de Sn e u∈Kn, seja VG (u) o espaço vetorial K estendido pela órbita ...
