摘要
The oscillation-quenching phenomena in coupled synchronous reluctance motor (SynRM) drives are analyzed. The basins of attraction of a single SynRM drive are studied. The multistability of the coupled systemis analytically and numerically studied. Due to the coexistence of multiple stable attractors, the coupled system can be stabilized at different equilibrium points under different initial conditions. The effects of the parameter mismatch and the coupling coefficients are analyzed. The stability mechanism of the coupled SynRM drives is analyzed. A new transition mechanism between different stable attracting regimes, e.g., a transcritical bifurcation, is analyzed in detail. By way of the parameter mismatch, the stability of the coupled system is maintained and the multiplicity of the operations of the coupled system is enriched.
