1. Towards Active Car Body Suspension in Railway Vehicles
Sammanfattning : Today, most railway suspension systems are passive. The most wide-spread exception isactive car body tilt systems, which are mounted in some high-speed trains. Replacingsome of the passive suspension components with active could reduce the weight and costof the vehicle. LÄS MER
2. On the Control of Transportation Networks with Delays
Sammanfattning : .... LÄS MER
3. Fixed structure LQ design with applications
Sammanfattning : This thesis deals mainly with the problem of designing structure constrained controllers (or fixed structure control design) which is a problem that occurs in many industrial control applications. In process industry for example, almost all control loops are closed with commercial PI controllers (which have specified structures). LÄS MER
4. 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.

5. Grid-Connected Voltage Source Converter - Control Principles and Wind Energy Applications
Sammanfattning : The thesis focuses on a forced-commutated voltage source converter (VSC) connected to a grid in a wind energy application. The work consists of four parts. The first part addresses the type of electrical system which should be used in a wind turbine. LÄS MER
