Chaos control of permanent magnet synchronous motors via unidirectional correlation

Permanent magnet synchronous motor (PMSM) displays chaotic oscillation with certain parameter values, which threatens the secure operation of the power system. An improved unidirectional correlation scheme is first proposed to control the undesirable chaotic behavior in PMSM. Simulation analysis shows that the presented control scheme is effective and one can control the PMSM to equilibrium point or non-equilibrium point by choosing appropriate correlation factor.
