| 摘 要： | 本文在复模态分析的基础上构造了用以表征处于任意周期性激振力作用下的转子-轴承系统最佳稳态响应的目标函数，由此出发解决了两类常见的最优控制力计算问题：当控制点一定而控制力大小及形式无强加约束时，作者提出的直接解法把对控制力的寻优最终归结为求解线性方程组问题，对于控制力形式及大小均受到强加约束的情况则按非线性规划采用Powell法及复合形法寻优；并给出了相应的算例。

| Abstract: | The objective function applied to express the optimum response of the rotor-bearing system is presented based on the complex mode analysis in this paper. Furthermore two kinds of the problems about the calculation of control forces are solved; In condition of non-restraint the optimization is treated as the evaluation of a set of linear equations,and the Powell and complex methods are used to calculate the restricted control forces.Numerical example is also presented relevantly. |
