Preshaping法在液面振动控制中的应用

The Application of Preshaping Method in Liquid Sloshing Control

针对液体运送过程中的液面振动问题,利用拉格朗日法推导出液体振动数学模型,讨论Preshaping法的应用.通过仿真得到以下结论:只有两个加速度输入量时间间隔及幅值满足某些要求,才能使匀速运动时的液面振动为零;否则就无法实现对液面振动的控制.

For liquid sloshing problem in liquid transfer,Lagrange method is used to derive the model of liquid sloshing,and the application of Preshaping law is discussed.With simulation,it is concluded that,only if the time intermission and scope of the two acceleration inputs satisfy some requirements,the sloshing of the liquid will be zero.Otherwise,the sloshing of the liquid can not be controlled.
