| 摘 要： | 针对双层气囊隔振装置高精度姿态平衡控制需求,提出多目标协同姿态控制方法。通过建立双层隔振装置动力学模型、充放气控制等效作用力模型,建立了控制响应特性分析模型。并基于多目标满意优化方法建立了多目标协同姿态控制方法,使得双层气囊隔振装置能够较好地适应上下层气囊隔振装置姿态耦合,实现姿态平衡控制,并可有效抑制结构弹性变形对姿态平衡控制的影响。在双层气囊隔振装置上验证了该控制方法的可行性。该方法将用于某型船舶大型发电机组双层气囊隔振系统,实现双层气囊隔振装置柔性支撑状态下的姿态平衡控制。

| Abstract: | A multi-objective coordinated attitude control method was studied in this paper, which aimed at the high precision attitude control of the dual layer air spring vibration isolation mounting. After establishing the dynamics model of dual layer air spring vibration isolation mounting and the equivalent model of charge and discharge control, the control response characteristic model was established. Then the multi-objective coordinated attitude control model was brought out based on the multi-objective satisfactory optimization method. This control method can adapt to the attitude control coupling of the superstratum and the substratum air spring vibration isolation mounting. And it can also restrain the elasticity distortion influence on the attitude equilibrium control. This control method was verified on a dual layer air spring vibration isolation mounting experimental system. It will be used in a dual air spring vibration isolation mounting for some large ship generator set and realize the high vibration isolation efficiency. |
