在本文中，提出了一项调查，演示了一种新的方法，使减少液体晃动，通过实施优化的运动轮廓在连续的操作速度范围内的应用。液体晃动发生在饮料的包装过程中。从建立动态过程模型开始，应用最优控制理论计算最优运动轨迹，使残余振动最小化。随后，检查由此合成的运动轮廓的操作速度依赖性的困难。讨论了一种将最优运动轮廓合并为运动规格特征图的方法，该运动规格特征图可由可编程逻辑控制器真实的实时执行。最后，这种新方法的成功证明了国家的最先进的运动轮廓和传统的运动实现的比较。
In this paper, an investigation is presented that demonstrates the application of a new approach for enabling the reduction of liquid slosh by implementing optimized motion profiles over a continuous range of operating speeds. Liquid slosh occurs in the packaging process of beverages. Starting by creating a dynamic process model, optimal control theory is applied for calculating optimal motion profiles that minimize residual vibration. Subsequently, the difficulty of operating speed dependency of the herewith synthesized motion profiles is examined. An approach in which the optimal motion profiles are consolidated into a characteristic map of motion specifications, which can be executed by a programmable logic controller in real time, is discussed. Eventually, the success of this novel approach is demonstrated by the comparison with state-of-the-art motion profiles and conventional motion implementation.
