11. Modeling and Optimal Control of Heavy-Duty Powertrains
Sammanfattning : Heavy duty powertrains are complex systems with components from various domains, different response times during transient operations and different efficient operating ranges. To ensure efficient transient operation of a powertrain, e.g. LÄS MER
12. Closed-Loop Control of HCCI Engine Dynamics
Sammanfattning : The topic of the thesis is control of Homogeneous Charge Compression Ignition (HCCI) engine dynamics. HCCI offers a potential to combine high efficiency with very low emissions. In order to fulfill the potential benefits, closed-loop control is needed. LÄS MER
13. Improving Fuel Efficiency of Commercial Vehicles through Optimal Control of Energy Buffers
Sammanfattning : Fuel consumption reduction is one of the main challenges in the automotiveindustry due to its economical and environmental impacts as well as legalregulations. While fuel consumption reduction is important for all vehicles,it has larger benefits for commercial ones due to their long operational timesand much higher fuel consumption. LÄS MER
14. Modelling and control of rotary crane systems
Sammanfattning : This thesis is devoted to the modelling and control of rotary crane systems. The goal is to design a control system that assists the operator to move a cargo without oscillations and to correctly align the cargo at the final position. LÄS MER
15. Control Lyapunov Functions : A Control Strategy for Damping of Power Oscillations in Large Power Systems
Sammanfattning : In the present climate of deregulation and privatisation, theutilities are often separated into generation, transmission anddistribution companies so as to help promote economic efficiencyand encourage competition. Also, environmental concerns,right-of-way and cost problems have delayed the construction ofboth generation facilities and new transmission lines while thedemand for electric power has continued to grow, which must bemet by increased loading of available lines.
