摘要
在Eric H.Maslen等人提出的偏流线性化方法的基础上,以12磁极弱耦合结构的径向磁力轴承为研究对象,提出了在执行器故障时电流重构的新方法,并利用ANSYS和MATLAB对该方法下得到的电流重构矩阵进行了仿真分析。从磁场的分布、电流分配矩阵的求解以及转子的动态响应等方面,验证了该方法在主动磁力轴承执行器容错控制上的可行性以及部分优越性。
Based on the bias linearization method, this paper researches weak coupled structure of 12-pole radial magnetic bearing. A new current reconstruction method is put ｜brward. Simulation analysis of the obtained current reconstruction by this method is carried out using ANSYS and MATLAB. This paper proves tile feasibility and some superiority of this method on active magnetic bearing actuator fault-tolerant control in terms of the distribution of the magnetic field the current allocation matrix solver and a rotor dynamic response.
