Autor: I. Safi, J. Boujelben, K. Tounsi, Z. Saoudi

Publikováno v: Indian Journal of Pure and Applied Mathematics. 53:701-719

Let $$\mathfrak {F}_{\lambda }^n$$ be the space of tensor densities of degree $$\lambda \in \mathbb {C}$$ on the supercircle $$S^{1|n}$$ . We consider the space $$\mathfrak {D}_{\lambda ,\mu }^{n,k}$$ of k-th order linear differential operators from

Modules of $${\varvec{n}}$$-ary differential operators over the orthosymplectic superalgebra $$\varvec{{\mathfrak {osp(1|2)}}}$$

We are interested in the study of the space of n-ary differential operators denoted by $$\mathfrak {D}_{\underline{\lambda },\mu }$$ where $$\underline{\lambda }=(\lambda _{1},\ldots ,\lambda _{n})$$ is acting on weighted densities from $$\mathfrak {

In this paper, the vector control of a parallel-connected two five-phase permanent magnet synchronous machines (PMSMs) drive supplied by a single current-controlled voltage source inverter is presented. This system consists of a two five-phase PMSMs;

Sensorless sliding mode control of a five-phase PMSM using extended Kalman filter

Autor: S. Barkat, E. Benyoussef, N. Bounasla, K. Tounsi

Publikováno v: 2016 8th International Conference on Modelling, Identification and Control (ICMIC).

The aim of this paper is to develop a sliding mode control (SMC) with extended Kalman filter (EKF) observer for a five-phase permanent magnet synchronous machine (PMSM). Using sliding mode approach, the resulting control scheme is going to have some

Un critére de transcendance de fractions continues dans Kp((X-1))

Autor: K. Tounsi, M. Mkaouar, M. Hbaib

Publikováno v: Journal of Number Theory. 116:140-149

There are uncountably many continued fractions of formal power series with bounded sequence of partial quotients, most of them are transcendental, but it is not very easy to give examples. This paper creates many families of such examples in an inter
