1. Conceptual design of hydraulic systems for automotive engine applications : simulation, optimisation and testing
Abstract : The main contribution of this thesis lies in the area of systems design, and especially of such systems that involve several engineering domains, so-called multidomain or heterogeneous systems. The design of these systems is concerned with a need for efficient tools, especially in the early conceptual phase of the development process. READ MORE

2. Control Strategy for Energy Efficient Fluid Power Actuators : Utilizing Individual Metering
Abstract : This thesis presents a solution enabling lower losses in hydraulic actuator systems. A mobile fluid power system often contains several different actuators supplied with a single load sensing pump. One of the main advantages is the need of only one system pump. This makes the fluid power system compact and cost-effective. READ MORE

3. Saving Energy in Construction Machinery using Displacement Control Hydraulics : Concept Realization and Validation
Abstract : In the sector of mobile hydraulics, valve controlled systems are predominant. In these systems the load force and speed are adjusted by control valves. In machines where multiple drives are used in parallel at extremely varying loads the energy efficiency of such systems is often compromised over large working regions. READ MORE

4. Exploring technologies for service provision in automotive winter testing
Abstract : Vehicles are becoming increasingly more complex in terms of, for example. Electronic Stability Program (ESP), Antilock Braking System (ABS), Traction Control System (TCS), and Active Rollover Protection (ARP), i.e. several different control systems that have to interact to perform well when driving.
