摘要

This paper reports that the performance of permanent magnet synchronous motor(PMSM)degrades due to chaos when its systemic parameters fall into a certain area.To control the undesirable chaos in PMSM,a nonlinear controller,which is simple and easy to be constructed,is presented to achieve finite-time chaos control based on the finite-time stability theory.Computer simulation results show that the proposed controller is very effective.The obtained results may help to maintain the industrial servo driven system's security operation.
