A novel E-core transverse-flux permanent magnet linear motor (TFPMLM) is proposed in this paper. Firstly, the operational principle and structural advantages of the TFPMLM are presented. Then it is simplified equivalently to one that can be resolved by Schwarz-Christoffel (SC) transformation to obtain its no-load characteristics such as flux density, PM flux linkage and cogging force instead of time-consuming...
In this paper, an original space-mapping technique, Kriging output space mapping (Kriging-OSM), is proposed. Based on an adaptive nonlinear corrective projection (Kriging model), the new technique makes the coarse model converge toward the fine model more effectively. It is firstly validated through a mathematical test function, and then applied to a 5-phase linear induction motor (LIM), represented...
For the design and analysis of an electrical motor, an analytical solution of electric and magnetic fields is barely achieved with the required accuracy. Although well-known finite element analysis (FEM) tools can compute these different multi-physical motor characteristics, coupling them can be difficult and often prohibitive in terms of computational time particularly in optimization processes....
Optimal design by means of finite element models is complex and time consuming. The Efficient Global Optimization (EGO) based on the progressive construction of a Kriging model used to drive the optimization problem allows for an affordable optimization time. In this paper, a linear induction motor (LIM) with double primaries for the subway system is designed, based on the validated 2D finite element...
The end effects are the particular sensitive difficulty to model linear drives. Moreover an electrical machine model which only considers single physical aspect is not sufficiently accurate. In this paper, 3D magnetic and thermal models are achieved taking into account the end effects and the multi-physical aspects. For the first step, the linear motor is studied as a braking system with different...
A new multirate fuzzy control technique for continuous-time nonlinear systems is presented in this paper. First, the lifted Takagi-Sugeno(T-S) fuzzy model of the plant is constructed subject to linear matrix inequalities (LMIs). Then, a multirate input controller for the multiple T-S linear models, based on the design of the local feedback controllers using optimal diskpole (D-pole) placement, is...
