摘　　要：给出了基于多输入多输出(M IMO)系统建模方法的电磁轴承柔性转子系统动态响应优化算法,通过数值仿真实例搜索得到系统最佳工作点。对电磁轴承柔性转子系统动态响应为目标函数的寻优规划的凸凹性进行了判定,对寻优结果作了鲁棒性分析,据此对寻优结果的可靠性给出了定量结论。计算与分析结果表明:电磁轴承柔性转子系统动态响应寻优规划为非凸规划,通过本文提出的优化仿真方法得到的系统最佳工作点为局部最优解且逼近全局最优解。The paper presented the dynamic response optimization algorithm for an electromagnetic beating＇s flexible rotor system that is based on the multi-input/multi-output （MIMO） system modeling method. It obtained the optimum operating point of the system through numerical simulation instance search. It also determined the concave-convexity of the optimization planning which takes the dynamic response of the electromagnetic ble rotor system as its objective function, and conducted the robustness analysis of the optimization reliability was quantitatively evaluated accordingly. The analysis results indicate that the optimization beating＇s flexi-results, whose planning of its dynamic response is non-convexity and that its optimum operating point obtained through the optimization method presented in the paper is a local optimum solution and approaches global optimum solution.
