1. Control Lyapunov Functions : A Control Strategy for Damping of Power Oscillations in Large Power Systems
Abstract : 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.

2. Formations and Obstacle Avoidance in Mobile Robot Control
Abstract : This thesis consists of four independent papers concerningthe control of mobile robots in the context of obstacleavoidance and formation keeping. The first paper describes a new theoreticallyv erifiableapproach to obstacle avoidance. READ MORE

3. Piecewise Linear Control Systems
Abstract : 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. READ MORE

4. Gain-Scheduled Controller Design
Abstract : This thesis is devoted to controller synthesis, i.e. to finding a systematic procedure to determine the optimal (sub-optimal) controller parameters which guarantees the closed-loop stability and guaranteed cost for uncertain nonlinear systems with considering input/output constraints, all this without on-line optimization.

5. Control and Analysis of Pulse-Modulated Systems
Abstract : The thesis consists of an introduction and four appended papers. In the introduction we give an overview of pulse-modulated systems and provide a few examples of such systems. Furthermore, we introduce the so-called dynamic phasor model which is used as a basis for analysis in two of the appended papers. READ MORE
