Robust suppressing chaos in permanent magnet synchronous motor with v/f control based on passivity theory
基于无源性理论自适应镇定具有v/f输入的永磁同步电动机的混沌运动

A passivity-based adaptive control law is presented, which transforms the permanent magnet synchronous motor (PMSM) with v/f controller into an equivalent passive system. It is proved that the equivalent system can be asymptotically stabilized at different equilibrium points without any influence of undeterministic parameters. Simulation results show the proposed control law is very effective and robust against the uncertainty in system parameters.
