16. Stochastic Event-Based Control and Estimation
Sammanfattning : Digital controllers are traditionally implemented using periodic sampling, computation, and actuation events. As more control systems are implemented to share limited network and CPU bandwidth with other tasks, it is becoming increasingly attractive to use some form of event-based control instead, where precious events are used only when needed.

17. Att anordna styrning : tillblivelse av en mångfald av styrteknologier
Sammanfattning : During the last couple of decades, management control studies have taken an increased interest in the multiplicity of management controls. Broadly speaking, research has focused on the consequences of management controls. However, research has rarely examined how a multiplicity of management controls comes to exist. LÄS MER
18. Design and Implementation of Object-Oriented Model Libraries using Modelica
Sammanfattning : This thesis describes basic models for thermo-fluid systems and the implementation of the models using a flexible object-oriented structure in the ThermoFluid library. Model libraries provide an excellent way to package engineering knowledge of systems to be reused by non-experts. LÄS MER

20. Learning control for flex-fuel CI engine and fuel cell
Sammanfattning : This thesis investigated the modeling and control problems in the context of the flex-fuel compression-ignition (CI) engine and fuel cell, which shows great potential in the transition from fossil fuel to renewable energy sources.The modeling parts included the flex-fuel engine combustion process and intake system, and the system scale fuel cell model.
