This paper describes the Sweaty II humanoid adult size robot trying to qualify for the RoboCup 2017 adult size humanoid competition. Sweaty came 2nd in RoboCup 2016 adult size league. The paper describes the main characteristics of Sweaty that made this success possible, and improvements that have been made or are planned to be implemented for RoboCup 2017.
In this TDP we describe a new tool created for testing the strategy layer of our soccer playing agents. It is a complete 2D simulator that simulates the games based on the decisions of 22 agents. With this tool, debugging the decision and strategy layer of our agents is much more efficient than before due to various interaction methods and complete control over the simulation.
In the future, the tool could also serve as a measure to run simulations of game series much faster than with the 3D simulator. This way, the impact of different play strategies could be evaluated much faster than before.
In the present work, nonlinearities in temperature compensating (TC) SAW devices are investigated. The materials used are LiNbO₃-rot128YX as the substrate and Copper electrodes covered with a SiO₂-layer as the compensating layer. In order to understand the role of these materials for the nonlinearities in such acoustic devices, a FEM simulation model in combination with a perturbation approach is applied. The nonlinear tensor data of the different materials involved in TC-SAW devices have been taken from literature, but were partially modified to fit experimental data by introducing scaling factors. An effective nonlinearity constant is determined by comparison of nonlinear P-matrix simulations to IMD3 measurements of test filters. By employing these constants in nonlinear periodic P-matrix simulations a direct comparison to nonlinear periodic FEM-simulations yields the scaling factors for the material used. Thus, the contribution of different materials to the nonlinear behavior of TC-SAW devices is obtained and the role of metal electrodes is discussed in detail.
Das Ziel des Vorhabens TempOLadung war die Entwicklung von optimierten Ladeverfahren für eine Lithium-Ionen-Batterie. Die Optimierung erfolgte unter besonderer Berücksichtigung des Temperaturverhaltens. Es wurden Methoden der mathematischen Modellierung und numerischen Simulation sowie der experimentellen Diagnostik eingesetzt. Kooperationspartner war das mittelständische Unternehmen Leclanché, ein traditioneller Batteriehersteller mit Produktionsstandort in Willstätt/Baden-Württemberg.
In dieser Arbeit werden die außentemperaturgeführte Vorlauftemperaturregelung (Standard-TABS-Strategie), ein Verfahren das auf einer multiplen linearen Regression basiert (AMLR-Strategie) und ein Verfahren, das unter dem Obergriff der modellprädiktiven Regelung (MPC-Strategie) zusammengefasst werden kann, untersucht. Anhand der Simulationsergebnisse und des Integrationsaufwandes in die Gebäudeautomation des Seminargebäudes wurde eine Fokussierung auf die AMLR-Strategie vorgenommen.
Im vorliegenden Bericht werden die Arbeiten und Ergebnisse der Hochschule Offenburg (HSOG) des Teilvorhabens 3 (TV3) dargestellt. Im Rahmen dieses Teilvorhabens war die HSOG direkt in das Teilprojekt 3 – berufsbegleitender Bachelorstudiengang Informatik/IT-Sicherheit – involviert. Für dieses Teilprojekt wurden Studieninhalte entwickelt und die Pilotierung für ausgewählte Jahrgänge durchgeführt.

In this study, a high-performance controller is proposed for single-phase grid-tied energy storage systems (ESSs). To control power factor and current harmonics and manage time-shifting of energy, the ESS is required to have low steady-state error and fast transient response. It is well known that fast controllers often lack the required steady-state accuracy and trade-off is inevitable. A hybrid control system is therefore presented that combines a simple yet fast proportional derivative controller with a repetitive controller which is a type of learning controller with small steady-state error, suitable for applications with periodic grid current harmonic waveforms. This results in an improved system with distortion-free, high power factor grid current. The proposed controller model is developed and design parameters are presented. The stability analysis for the proposed system is provided and the theoretical analysis is verified through stability, transient and steady-state simulations.
