The design of a CACC system and corresponding experiments are presented. The design targets string stable system behavior, which is assessed using a frequency-domain-based approach. Following this approach, it is shown that the available wireless information enables small inter-vehicle distances, while maintaining string stable behavior. The theoretical results are validated by experiments with two...
Optical discs, including Compact Discs (CDs), Digital Versatile Discs (DVDs), and Blu-ray Discs (BDs), can get cracked during storage and usage. Such cracks commonly lead to discontinuities in the data track, potentially preventing reading of the data on the disc. The aim of the present paper is to improve tracking performance of the optical disc drive in the presence of cracks. A Hankel Iterative...
The manipulation of samples in atomic force microscopes (AFMs) is often performed using piezoelectric actuators. In this paper, a metrological AFM with a 3 degree-of-freedom (DOF) stage driven by piezo-stack actuators is considered. The piezo actuators exhibit hysteresis, which can change the system dynamics and/or acts as a non-linear disturbance on the system. This deteriorates the performance of...
