“…5. In Figure 5 it is shown clearly how the phase flux linkage estimated by the selected model of structure (3,8) matches perfectly the true one. The consistency and accuracy of this model are confirmed by the estimation and test errors made on the phase flux linkage when the model is subject to the estimation and test input data given in Table II.…”

A new nonlinear grey box (NLGB) model of switched reluctance motors (SRM) based on first modeling principles is developed. This model is obtained by representing the inductances of the machine phases by a series of functions modeling the periodic variation of the permeance of the phase magnetic circuits with respect to the rotor position, weighted each by a smooth function taking into account the flux saturation. The structure of this model is obtained by expanding the periodic behavior and saturation phenomenon as Fourier series and Legendre polynomials respectively, and its parameters are estimated from input-output data by minimizing the estimation error of the phase flux linkage given in a linear regression form with respect to the searched parameters. The consistency and accuracy of the developed NLGB model are confirmed by simulation within an automotive application.

“…Many experimental, numerical, grey-box namely analytical, and black-box models of SRMs have been investigated following various approaches, see [8,9,10], and references therein. In the present study the focus is made on the modelling and parameter estimation of current controlled SRM drives by following the grey box modelling approach.…”

“…Multiphysics simulation from ANSYS provides powerful simulation tools for solving industry's toughest multiphysics challenges. It also includes solutions for both direct and sequentially coupled physics problems including direct coupledfield elements (Souiyah et al, 2009).In order to analyze the submersible SRM by ANSYS Workbench, the geometrical model of the motor was plotted at first and appropriate materials are assigned to different regions (Ustun, 2009;Sundaram et al, 2009). The SRM has a complicated configuration and it is cumbersome and time-consuming to draw the geometrical model every time before simulation.…”

Problem statement:The Switched Reluctance Motor (SRM) is an old member of the Electric Machines Family. It's simple structure, ruggedness and inexpensive manufacturing capability make it more attractive for Industrial applications. Now, the applications of switched reluctance motors in various industrial fields are tried by many engineers. However, switched reluctance motors are not used so far in submersible underwater motor for agriculture purposee. The torque developed by an SRM is dependent on the change of flux-linkage and rotor position. The flux linkage characteristic of the motor is required to make the control circuit. Since the SRM is non-linear in nature, estimation and calculation of the flux linkage characteristics is very difficult. Approach: With the flux tube method concept a simple algorithm is being developed in a MATLAB. ANSYS Software is used to determine the flux distribution at various rotor positions. Results: The aligned and unaligned flux linkage values for theoretical calculation at a current of 7 A is 72.7 mwb and 13.79 mwb respectively. With FEA simulation the obtained value is 92.73 mwb and 19.175. Conclusion: In this and, a simplified method for the determination of flux linkage characteristics of submersible SRM using MATLAB has been presented. The obtained value has been validated with the ANSYS FEM method. the calculated unaligned and aligned inductance values of a 4-phase, 3 hp, 220 V Submersible SRM using simplified MATLAB method very much matches with the ANSYS FEM Method.

“…The permanent magnet materials are also used in brushless DC generator, so its cost is also high. The switched reluctance (SR) motor drive had been applied with high reliability for many years [1][2][3][4][5][6][7][8][9]. It can also be used as generator system [10][11][12].…”

“…The switched reluctance (SR) generator system consists of an SR generator body, power converter, and controller [1][2][3][4][5][6]. The generator rotor is only laminated by electrical steel, and there are brushless, no winding, no permanent magnets on the rotor and concentrated windings on the stator.…”

This paper presents nonlinear simulation model of switched reluctance (SR) ocean current generator system on MAT-LAB/SIMULINK with describing the structure of generator system. The developed model is made up of main model, rotor position calculation module, controller module, gate module, power converter module, phase windings module, flux-linkage module, torque module, and power calculation module. The magnetization curves obtained by two-dimensional finite-element electromagnetic field calculation and the conjugated magnetic energy graphics obtained from the three-dimensional graphics of flux linkage are stored in the "Lookup Table" modules on MATLAB/SIMULINK. The hardware of the developed three-phase 12/8 structure SR ocean current generator system prototype with the experimental platform is presented. The simulation of the prototype is performed by the developed models, and the experiments have been carried out under the same condition with different output power, turn-off angle, and rotor speed. The simulated phase current waveforms agree well with the tested phase current waveforms experimentally. The simulated output voltage curves agree well with the tested output voltage curves experimentally. It is shown that the developed nonlinear simulation model of the three-phase 12/8 structure SR ocean current generator system is valid.
