The influence of the controller’s parameters on the characteristics of the ultra-resonant area of the active magnetic bearing system

摘要: 本文对PID控制的单自由度电磁轴承-转子系统由于力-电流/位移的非线性特性所引起的非线性振动进行了分析研究,并对控制器参数改变时,系统在三次超谐共振区的特性进行了分析.

Abstract: The nonlinear vibration caused by the nonlinear characteristics of displacement of force and current within the mono-freedom degree active magnetic bearing and rotor system controlled by PID is investigated in this paper.The characteristics of the three-time ultra-resonant area is also analyzed when the controller's parameters have been altered.
