| 摘 要： | 由基本的动力学关系建立了用钢带轮传动反射镜的陀螺稳定平台的控制回路数学模型。讨论了弹性效应的特性并给出了一个相应的稳定性判据。指出反射镜的角振动频率是限制平台动刚度提高的一个障碍,并提出了提高稳定精度的设计措施。此结果已得到了成功的工程应用。

| Abstract: | In this paper a mathematical model is derived from the basic dynamicrelations for the control loop of the gyrostabilized platform which drives a mir-ror with belt pulley.With this model the feature of the elastic effect is discus-sed and a corresponding stability criterion is obtained.The analysis shows thatthe natural frequence of the angle vibration of mirror is an obstruction to raisethe dynamic rigidity of the platform.Finally,from the conclusions,some designmethods for raising the stabilizing accuracy are proposed.The results obtained inthis paper have been used successfully in engineering. |
