This work addresses inverse dynamic games, which generalize the inverse problem of optimal control, and where the aim is to identify cost functions based on observed optimal trajectories. The identified cost functions can describe individual behavior in cooperative systems, e.g. human behavior in human-machine haptic shared control scenarios.

Novel THz device concepts and signal processing schemes are introduced and experimentally confirmed. Record-high data rates are achieved with a simple envelope detector at the receiver. Moreover, a THz communication system using an optoelectronic receiver and a photonic local oscillator is shown for the first time, and a new class of devices for THz transmitters and receivers is investigated which enables a monolithic co-integration of THz components with advanced silicon photonic circuits.

Diese Arbeit beschreibt den neuartigen Einsatz von breitbandigen kontinuierlichen Frequenzweichen für die Parallelisierung von Millimeterwellen-On-Wafer-Messtechnik durch die Integration in On-Wafer-Messspitzen. Eine modellbasierte Methode für den effizienten Entwurf von Frequenzweichen mit einer Vielzahl einstellbarer Parameter ermöglicht die erstmalige Realisierung einer DC – 110 GHz – 170 GHz Frequenzweiche.
This work describes the novel use of broadband continuous diplexers that could be integrated into on-wafer probes to parallize millimeter wave on-wafer measurement equipment. A model-based method for the efficient design of diplexers with a large number of adjustable parameters allows the realization of a DC – 110 GHz – 170 GHz diplexer for the first time.

Das menschliche Auge kann sich aufgrund seines Dynamikumfangs innerhalb kürzester Zeit an verschiedenste Lichtsituationen anpassen. Ist der Dynamikumfang des Auges nicht ausreichend, kommt es zur Blendung. Um die Auswirkungen auf die Sehleistung und deren Verlauf zu beschreiben, fehlt eine geeignete objektive Messmethode. Diese wurde im Rahmen dieser Arbeit entwickelt und validiert.
Due to its dynamic range, the human eye can adapt to a wide variety of light situations within a very short time. If the dynamic range of the eye is insufficient, glare occurs. There is no suitable objective measurement method to describe the effects on visual performance and its course. This was developed and validated as part of this work.

In dieser Arbeit wird ein auf Haptic-Shared-Control basierendes Konzept vorgeschlagen, welches Menschen bei der Übernahme einer Aufgabe von einer Automation, wie beispielsweise am Ende einer hochautomatisierten Fahrt, unterstützt. Die Beschreibung der Interaktion durch zeitvariante Differentialspiele erlaubt einen modellbasierten Reglerentwurf sowie die Schätzung der aktuellen Bereitschaft des Menschen. Der Nachweis von performanteren und sicheren Transitionen erfolgt in mehreren Experimenten.
This work proposes a concept based on haptic-shared control to assist humans in taking over a task from an automation, such as at the end of highly automated driving. The description of the interaction by time-variant differential games allows a model-based controller design as well as the estimation of the human's current readiness to take over. Several experiments demonstrate more performant and safe transitions with the new approach.

As the share of renewable generation increases in electric grids, the traditionally heat driven operation of combined heat and power plants (CHPs) reaches its limits. Thermal storage is required for a flexible operation of CHPs. This work proposes three novel methods to use a heating grid as thermal storage by exploiting its thermal dynamics. These include the first approach proving global optimality, a novel linear formulation of grid dynamics and an easily real world applicable approach.
