Constrained iterative learning control of liquid slosh in an industrial packaging machine

Considers the problem of moving a container with liquid without too much slosh in an industrial packaging machine, There is no measurement of the slosh available in the machine to use for control, it is however possible to measure the slosh in a testbed. The problem is to determine the shape of the open loop acceleration reference that is programmed in the motion control system that controls the movement of the containers. In the paper the acceleration reference is calculated using iterative learning control where the results of an experiment are used to refine the acceleration reference to be used in the next iteration.
