摘要
对于磁悬浮模型的稳定控制,工程上常用的方法是将非线性磁悬浮模型在工作点附近进行泰勒展开,忽略高阶项以后,得到线性化模型,但这会影响到系统的稳定。本文建立了磁悬浮系统的动态模型,并采用状态反馈精确线性方法对其进行线性处理。设计了以电流作为输入控制量的闭环控制器,并通过Matlab仿真实验,证明了该方案的可行性、实用性。
For the stability control of single magnetic levitation system （SMLS）, the method engineering commonly used is to expand around the equilibrium point by Talor series, ignoring higher order items.But it affect the stability of system. The nonlinear dynamic mathematic model of SMLS is set up,and the linear mathematic model of SMLS is designed through the method of feedback linearization.A current closed loop controller is designed,and its effect and feasibility are proved by the Simulink of Matlab.
