Abstract:

Chaotic phenomena in permanent magnet synchronous motors (PMSM) can be observed when parameters in PMSM are in a certain range. In general, chaos will degrade the performance of PMSM or even collapse the system. In order to suppress the chaos in PMSM, adaptive and cascade adaptive control scheme are utilized in this paper. Faithful model of PMSM is not necessarily required by using adaptive control based on dynamic compensation mechanism. By choosing appropriate controller parameters, chaos will be eliminated and the response speed can be tunable. Numerical simulation results are given out to confirm both of the adaptive control approaches are valid in chaos control of PMSM.
