摘要
针对主动磁轴承-转子系统在运行中存在的不平衡扰动和非线性干扰问题,结合主动磁轴承-转子系统工程化的需要,提出了一种离散模糊自适应滑模控制的方案,建立了4自由度径向主动磁轴承数学模型,设计了离散非线性跟踪微分器,对磁轴承-转子系统进行仿真。结果表明,该系统的不平衡扰动和非线性干扰得到了抑制,实现了系统的高精度鲁棒控制。
In view of unbalance disturbance and nonlinear disturbance problem about active magnetic bearing -rotor system during operation,a discrete fuzzy self -adaptation sliding mode control scheme is presented combining with en-gineering need of active magnetic bearing -rotor system.The 4 -freedom mathematical model is established for radial active magnetic bearing.The discrete nonlinear tracking differentiator is designed,and the magnetic bearing -rotor sys-tem is simulated.The results show that the unbalance disturbance and nonlinear disturbance of system is suppressed, and the high precision robust control of system is realized.
