摘要
为了实现液体传送过程中的液面制振 ,提出了一种基于CFD计算流体动力学模型和混合波形方式基础上的控制系统 .通过计算机模拟仿真 ,找出液体制振的关键———液体的振动固有频率 (即谐振频率 ) ,然后考虑时域和频域的混合波形方式 ,设计出制振优化控制系统 .
This paper presents a control system design of liquid container transfer system by using computational hydrodynamic model. By using computer aided simulation, sloshing (liquid vibration)phenomena are analyzed and liquid resonance frequency in container is identified which plays an important role for controller design. The optimized controller is designed by hybrid shape approach considering both time and frequency characteristics. The effectiveness of the proposed control system is shown through simulation and experiments.
