No full textA distributed anisotropy linear reluctance motor
No full textThe behaviour of a distributed anisotropy linear reluctance motor is investigated, from the viewpoint of its magnetic characteristics, d-q parameters, thrust production and cross d-q axis coupling due to saturation phenomena. It is shown that, accounting for quadrature air gap induction, the mathematical model of the linear reluctance motor cannot be immediately deduced from that of the rotating motor, as is the case of the induction motor. Therefore a dedicated mathematical modelling of the linear anisotropic structure is presented. The air gap inductance versus relative position is determined by solving a system of differential equations with variable coefficients. The reluctance thrust is then evaluated, taking into account the static end effects. The coupling between d and q-axis reactances, due to saturation phenomena, is numerically evaluated. Finally, the test results of a four pole prototype motor are presented
Tabu search metaheuristic for designing digital filters
No full textThis paper deals with the application of a Tabu Search (TS) metaheuristic to the design of digital filters, with coefficient values expressed as the sum of power of two. The performances of the algorithm are heavily affected by the choice of its parameters, which in turn are related to different implemented strategies. The tuning of these parameters has been performed after many tests. The results of the proposed technique are compared to those obtained by simply rounding the optimal values of coefficients obtained by means of Remetz algorithm, and to those obtained using a simulated annealing algorithm
