Position Sensorless Control of Switched Reluctance Motor Drives Based on a New Sliding Mode Observer Using Fourier Flux Linkage Model

A Novel Predictive Torque Controller for Switched Reluctance Motor Drives

“…It can be seen from ( 1)-( 3), it is the key to establish the SRM model to obtain the flux-linkage characteristics accurately. An analytical flux-linkage model presented in Refs [24][25][26] was adopted in this study. The analytical model approximates the flux-linkage in the form of Fourier series and polynomial multiplication, which can be expressed as…”

“…It can be seen from (1)–(3), it is the key to establish the SRM model to obtain the flux‐linkage characteristics accurately. An analytical flux‐linkage model presented in Refs [24–26] was adopted in this study. The analytical model approximates the flux‐linkage in the form of Fourier series and polynomial multiplication, which can be expressed as $$$$ {\psi}_p\left({i}_p,\theta \right)=\sum \limits_{n=0}^N{\lambda}_n\left({i}_p\right)\mathit{\cos}\left({nN}_r\theta \right)\kern1.6em with\kern0.5em {\lambda}_n\left({i}_p\right)=\sum \limits_{m=0}^M{b}_{nm}{i}_p^m $$$$ where N and M are the order of Fourier series and polynomial, respectively.…”
