摘要
建立了电磁轴承柔性有质转子系统计入陀螺、阻尼、轴-径向动力耦合及机械-电磁-控制系统耦合等影响的动力特性分析计算数学模型。导出了多变量控制系统的标准化系统矩阵向量方程。以系统仿真响应为目标,通过复合寻优方法实现了系统最佳工作区(点)的求解。对优化仿真结果与试验现场调试结果进行了对比分析。
A dynamic analysis model of flexible rotor magnetic bearing system is founded considering gyroscopic effect, damping, axial-radial dynamic couplings and machine-electromagnetism-control system couplings. The standard system matrix vector equations on multi-variable control system are educed. The objective functions are system simulation responses. The optimum operating scopes (points) are obtained by complex optimization methods. The results of optimum simulation are compared with those of experiments and analyzed as well.
