Collective Dynamics of Coupled Synchronous Reluctance Motor Drives

The collective dynamics under different coupled strengths in the coupled synchronous reluctance motor drives is presented in this paper. With variation of the coupled strengths, the coupled system exhibits rich dynamical phenomena such as amplitude death, periodic anti-synchronization and complete synchronization. By the amplitude death the coupled synchronous reluctance motor drives can be stabilized into the equilibrium. The attracting regimes of the coupled system are studied. The attracting behaviors with different initial conditions are analyzed. Due to the coexistence of multiple attractors, the coupled system can be controlled to different fixed points under different initial conditions. The multiplicity of the operation of the coupled system is enriched. The secure operation of the coupled drives can also be maintained.
