Abstract

In the present work a systematic approach is presented. With this approach it is possible to take concerted simplifications in building models of power train systems of mobile machines. The adopted systematic simplifications are aimed essentially of reducing the order of the system. The basis for this is the introduction of hydraulic replacement elements. Their mathematical structure is based on reduced-dynamic, stationary and event-oriented considerations.

Abstract

Energy management strategies are developed for hybrid drive systems in which multiple actuators are interacting with an accumulator. The strategies are derived using a universal approach for efficiency assessment of control decisions. Therefore the accumulator’s power flow is weighted by its impact onto the internal combustion engine. Experimental studies with a telescopic handler show up to 10% of measured fuel savings.

Abstract

This work discusses the question, how far mobile machines have evolved to complex systems today. Some resulting problems of the conventional strictly decentralized control are revealed. An alternative is the observer/controller architecture, which is transfered to a concrete mobile machine in the simulation.

Abstract

The book deals with the topic of mobile machines. In the first part the fundamentals of the machines are treated. The structures and different topologies used in the machines are described in detail. Starting from the energy source, the energy is followed up via engine to the power take-offs. In the second part selected mobile machines from the different areas are presented.

Abstract

This work describes an optimization concept for mobile antenna systems. The so-called antenna synthesis determines optimal fixed antenna radiation patterns with the help of simulated or measured transmission channels. These radiation patterns increase the spectral efficiency and the reliability of the antenna system compared to conventional antennas with omnidirectional radiation patterns. Therefor the antenna systems are matched as best as possible to the predominant directions of the channel.

Abstract

Mobile robotic systems need to perceive their surroundings in order to act independently. In this work a perception framework is developed which interprets the data of a binocular camera in order to transform it into a compact, expressive model of the environment. This model enables a mobile system to move in a targeted way and interact with its surroundings. It is shown how the developed methods also provide a solid basis for technical assistive aids for visually impaired people.

Abstract

The drive line of the working equipment of mobile machines is mainly composed of fluid power systems. Electro-hydraulic components facilitate the development of innovative Flow-on-Demand hydraulics. In these systems the oil flow of the pump is derived from the consumer requests and directly set in an open-loop control. Principle related power dissipation is reduced. Additionally, faster system response improves machine operability and ease of use.

Abstract

For human-robot-interaction, this work proposes a method for monitoring the complex, dynamic environment of the robot. The robot motion is controlled based on the concept of nonlinear model predictive control. The controller considers the detected obstacles and intended or unintended contacts of the robot with its environment so that undesired collisions are avoided and an adequate reaction to contacts is achieved. The proposed approaches are analyzed on a mobile manipulator.

Abstract

Currently, companies have covered their business processes with stationary workstations while mobile business applications have limited relevance. Companies can cover their overall business processes more time-efficiently and cost-effectively when they integrate mobile users in workflows using mobile device features. The objective is a framework that can be used to model and control business applications for PLM processes using mobile device features to allow a totally new user experience.
