| 摘 要： | 在主动控制转子振动的过程中,支承刚性的改变必然伴随着转子两个稳定运动状态间过渡的瞬态过程。用时变系统理论研究了瞬态振动的特性及其影响因素,设计了时变控制器。结果表明,瞬态响应是转子主动控振中不可忽视的因素。时变控制器可大大减少瞬态响应的影响。

| Abstract: | The transient response and its influenee factors are investigated and a method for attenuating the transient response has been developed by means of a time vacying model.The system gain matrix is obtained by choosing the weighting matriees and solving the time varying Riccati equation. Control forces are applied to the system via a feed back loop.Comparisons of responses with control and without control are made.The results show that the transient and steady-state responses are significantly suppressed in the close loop system and control forces are very small. |
