Robustness to Jitter in Real Time Systems

Communication delays in real time systems cause detoriation of the control performance of the closed loop system. To investigate this problem a process with varying delay is studied. Control of a motor in presence of delays is studied for different delay models. Design equations are derived based on polynomial design. The design depends on the designer's choices, i.e. desired closed-loop behav

Programpaket för uppsättning och intrimning av PID-regulatorer

To handle controllers conveniently in PLC systems, a host computer and a program with a graphical user interface for setting up and tuning controller parameters facilitate this task. This report describes the development of such a program at Beijer Electronics in Malmö. This tool for use with Mitsubishi's PLC systems supports logging of up to 32 simultaneous control loops which of one of these

Active Damping of Subsynchronous Resonance

This report deals with the damping of sub-synchronous oscillations in power systems. The method is based on estimation of the generator rotor angle and shaft speed, by measuring the line current and the voltage across a phase-compensating series capacitor. These two signals are probably not sufficient, so a line-to-ground voltage measurement is added. However, this means increased costs. A thyrist

Modeling of Multibody Systems in Omola

A library of Omola models for modeling and simulation of mechanical multibody systems in three dimensions has been developed. It contains common basic mechanical components such as springs and joints of different kinds. Omola is an object-oriented modeling language and supports flexability. The modularization and inheritance concepts supports easy modification of models. The library contains abstr

Adaptive Control of Systems with Dead Zones

In this paper an adaptive system to control processes affected by dead-zone nonlinearities, based on a nonlinear compensation, has been studied. The adaptive control schemes ensure boundedness of the close-loop signals and reduce the tracking error. The main goal was to understand the problem in details, analyzing the different situations and difficulties that this nonlinear compensation might in
