The topic of this publication is the design of interval observers for LPV systems under consideration of parameter, input and output uncertainties that are described by bounded intervals. In the course of the design, also time-varying bounds of the parameter intervals are considered representing the case when parameters are measured with an unknown but bounded measurement error. In this case, an existing...
FEM chip formation simulations and machining tests of orthogonal cutting were undertaken in order to investigate the influence of cutting speed and tool wear on cutting force, chip segmentation frequency, and residual stress state for Ti-6Al-4V. In addition, acoustic emissions, measured by a piezoelectric sensor adapted to the tool shank, were analyzed to extract chip segmentation frequency in-process...
