磁悬浮轴承的非线性模型仿真研究

本文针对磁悬浮轴承的非线性建模，进行了控制系统的仿真研究。利用SIMPLORER仿真软件，建立了磁悬浮轴承的线性系统模型和非线性系统模型，分析了PID参数对系统稳定性的影响，对比了两种模型的PID参数的稳定范围。仿真验证了非线性模型参数更接近于实际系统参数。

Simulation Study of the Non-linear Model of Active Magnetic Bearing

In this paper a active magnetic bearing control system for non-linear model are simulated and studied.By using the simulational software SIMPLORER, linear and non-linear models of active magnetic beafig are built, the influence of parameter PID to the systemic stability are analyzed, and the steady areas of the parameter PID of different models are contrasted. The parameter PID of the non-linear are validated which is more similar to the real system than the linear system by simulation.
