Hybrid reluctance actuators for high precision motion

Next-generation high-quality motion systems require high-precision actuators with higher energy efficiency and larger force to improve the system throughput. Particularly, actuators with a motor constant higher than comparable voice coil actuators are highly desired. This project investigates hybrid reluctance actuators (HRAs) with guiding flexures as a promising candidate of next-generation systems. Read more →

Modeling, observer design, and control of continuous strip processing lines

In continuous strip processing line, steel strips are thermally and mechanically processed as well as surface coated (e.g. galvanized). In this project, observer and control concepts for continuous galvanizing lines are developed. Additionally, controllers for laboratory facilities to develop new process technologies (e.g. laboratory furnaces) are designed. Read more →

Optimal Control of pneumatic linear drives

This project aims at robust but cost effective solutions for the most common industrial application of pneumatic linear drives, namely point-to-point movements. For this a suited setup for reduced investment costs is chosen. The setup consists of four leakage free fast switching valves, which are interconnected to two half bridges, three low cost pressure sensors and two small piecewise position sensors. The combination of modern control concepts and tailored trajectory planning strategies allows to move the drive even under typical variations in the working conditions. Subsequently the developed concepts are validated by means of measurements on lab test benches. Read more →

Modeling, observer and control design of a tandem hot strip rolling mill

Rough-rolled steel plates are rolled in a tandem hot rolling mill to strip with a final thickness. This thickness should accurately and uniformly correspond with the desired value. To satisfy this requirements and to ensure a stable strip travel, model-based control concepts are developed in this project. Read more →

Soft landing strategies for electromagnetic fast-switching valves

This project is concerned with the development of a soft landing control strategy electromagnetic valves. The main goal is to guarantee time-optimal switching of the valves with minimal impact velocity of the plunger at the limit stops. Thus, the approach combines the benefits of fast response and low maintenance intervals. Read more →

Automated Handling of Highly Deformable Materials

In this project, a prototype of a handling system is set up and the potential of modern model-based control to handle limp materials is examined. The concepts are applicable to many other issues, such as the automated lamination of large vinyl sheets, textile handling, etc. Read more →

Fundamentals of opto-mechatronic systems (OMC)

Currently innovation is taking place at the border of disciplines rather than in one individual field of engineering. This particularly holds for application domains that span more than one field of engineering, since a high level of system integration from different disciplines provides solutions that a single domain alone cannot provide. As an example, the combination of optics and mechatronics form the interdisciplinary field of opto-mechatronics. Read more →

Scanning optical point- and line-sensor (SOS)

To overcome the limitation for better productivity and reliability of production in this project, a rotating or steering mirror scans the sensor’s optical point or line over a product surface, targeting triangulation, confocal, and color sensors. Read more →

Characterization of highly divergent optics (DOC)

Opto-mechatronic devices such as triangulation sensors or polychromatic confocal sensors project focused light beams onto the surface of the measuring object. Assessing the properties of the focused beam is essential as they are directly related to the achievable measurement resolution and precision of the opto-mechatronic device. Read more →
