The present paper deals with the problem of modeling liquid slosh occurring in the packaging process of containers filled with liquid. Sloshing effects are induced by one-dimensional intermittent motions and are undesired due to the necessity of quality control processes, such as weighing. Therefore, motion optimizations are often applied with the intention to minimize the residual vibrations. Valid process models are required to do so. The aim of this paper is to derive models for describing the liquid slosh behavior for different motions and for common practical circumstances, e.g., different container geometries as well as machine operating speeds, and to state the model's limits of use. Known model approaches are discussed, and their assumptions are reviewed experimentally. This leads to a set of limited ranges of operating speeds in which the applied models' assumptions are valid. The models are derived for these sets from experimental data, and a comparison is executed that enables the determination of the models' validity concerning their operating speed dependency. Finally, the validity of the derived models is investigated by comparing their predictive efficiency of describing the vibration for different motion profiles.

“…Another possibility is the modeling with concentrated parameters and physical substitution models such as the pendulum model, also discussed in [7]. This approach leads to an ordinary differential equation of order two, which can be easily considered in common motion optimization algorithms in an efficient way [16,17].…”

A dynamic output feedback controller involving delays is designed for a cart -pendulum system with active and passive vibration absorption. The active vibration absorption involves a couple of Delayed Resonators feeding back the resonators' acceleration. The active vibration cart -pendulum system is modeled here as a neutral time delay nonlinear system. The proposed design technique aims to suppress the pendulum angle variations while simultaneously to achieve forward cart velocity command following. The good performance of the proposed controller is demonstrated via computational experiments.

A simulated annealing controller for sloshing suppression during the transfer of a liquid using a vehicle with active and passive vibration absorption is proposed. The proposed design technique aims to suppress sloshing induced by vehicle vibrations due to force disturbances applied on the liquid carrying vehicle due to road surface unevenness, while dealing with practical problems like the lack of measurements of the liquid's motion within the tank. Active vibration absorption is achieved with the use of a couple of Delayed Resonators. Despite the high complexity of the system's model, the proposed technique results in an easy to implement linear static measurement output feedback controller with satisfactory performance with respect to sloshing suppression.
