Analysis of Flux-Linkage Characteristics of Switched Reluctance Linear Generator

Thermal performance analysis of the double-sided linear switched reluctance motor

“…As an example, figure 4a shows the force (3) as function of PS and J for m=4 phases. In general, for all of the LSRM(m,PS) designs, the maximum force is achieved at J=20 A/mm 2 and PS=10mm, which are the limit values. Figure 4b shows the temperature rise (12).…”

Piecewise Affine Magnetic Modeling of Permanent-Magnet Synchronous Machines for Virtual-Flux Control

“…I P ⊆ I is the set of measured [12][13][14][15][17][18][19][20], simulated [12,13,17], or estimated [8][9][10] current points that will be used to create the PWA MM. The corresponding flux set Λ p must also be known.…”

“…The focus of this study is the flux linkage magnetic model (MM) of the PMSM and the modeling of the stator inductance parameters. To build an offline MM, the current and flux values are processed offline, and continuous inductance functions are created using linear interpolation, Hermite spline interpolation [15,17,18], polynomials [13,19], piecewise nonlinear functions [14], nonlinear functions [12,20], or piecewise affine functions [21]. The results of these methods vary greatly in their properties, as summarized in Table 1 (the MM accuracy for the linearized inductance, spline-interpolated LUT, and piecewise linear methods is shown in Section 5).…”

Control Strategy of Parallel Systems with Efficiency Optimisation in Switched Reluctance Generators

“…To enhance the reliability, anti-interference ability and generation capacity of power generation system (Chang and Liaw, 2008;Sun et al, 2011;Xiong et al, 2009), SRGs are connected in parallel on the basis of improving the generation capacity of a single SRG so as to fulfil the actual demand of various loads. However, the generator overload and uneven power distribution caused by different external characteristics of each generator usually make performance of parallel system to undergo degradation (Chen et al, 2014;Zhou et al, 2019). Therefore, addressing the question of how to rationally allocate power generation between each SRG is the key to design a parallel control strategy (Panov et al, 2008;Schofield et al, 2009;Song et al, 2014).…”
