Abstract: We used disturbance observer to study the adaptive sliding mode synchronization of permanent magnet synchronous motor (PMSM) fractional-order chaotic system. We considered uncertainties and unknown external disturbances through the fractional-order disturbance observer and verified the obtained conclusion through numerical simulation. The results show that the master-slave system of the PMSM chaotic system achieves sliding mode synchronization under  appropriate disturbance observer, sliding mode function, controller and the adaptive law.

Key words: permanent magnet synchronous motor system, sliding mode, chaos, disturbance
