Abstract:This Master thesis is done at the Control Lab of the University of Twente. One of the topics at the Control Lab is the design and control of mechatronic systems. Within this field of interest I have chosen my Master thesis. Many products are made out of different raw materials. These raw materials should be mixed together in the right proportions. To do so, the materials should be dosed into a weighting scale where the weight can vary form a few grams up till several tons. Problems arise when dynamic effects, caused by falling material, lead to errors during measurements. The material that is situated between the valve and the sand-pile, will provide a rest-drop when the valve is closed. To preserve the accuracy slow dosing of the weight to a desired value is a solution. However, a weighting process is always a compromise between speed and accuracy. This thesis provide modeling and simulation methods to design dynamic models of granular heaping. Methods will be reviewed for their usefulness. These models should provide the insight of the dynamics of granular heaping. The goal of this project is to come up with a fast and accurate dynamic weighting process.
