1. Analysis and Design of Hybrid Systems
Sammanfattning : Many physical systems today are modeled by interacting continuous and discrete event systems. Such hybrid systems contain both continuous and discrete states that influence the dynamic behavior. LÄS MER
2. 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.

3. Piecewise Linear Control Systems
Sammanfattning : This thesis treats analysis and design of piecewise linear control systems. Piecewise linear systems capture many of the most common nonlinearities in engineering systems, and they can also be used for approximation of other nonlinear systems. LÄS MER
4. Discrete-time stability analysis of hybrid systems : a Lyapunov approach
Sammanfattning : .... LÄS MER
5. Branch Identification in Elastic Stability Analysis
Sammanfattning : In this thesis, methods to determine the static postbuckling behaviour of elastic structures undergoing large deformations, are considered and developed. Since the governing non-linear equations usually becomes too complex to be handled analytically, the main focus has been on developing methods that can be incorporated into a numerical solution scheme, such as the finite element method.
