Modeller och regulatorer för en industriell gasturbin

The goal of this work is to use basic physical laws to construct a model and a controller for an industrial gas turbine. The model shall simulate all of security and controlling interesting process variables, with resonable accurancy. The controller shall use the process up to the limits to get it as fast as possible at load changes. An unlinear model for a gas turbine STAL GT-120b has been establ

Atlas Copco Central Regulator RD100 Electronics and Systems

The aim of this report is to provide an extensive description of regulator RD100, and its subsystems, from an electrical point of view. The report is written in a step-like manner in order to suit various kinds of readers, from those who only need a basic knowledge about the regulator, to those who will be eventually redesigning the whole regulator or parts thereof, to make it meet future demands

Samkörning av motorer

In this report studies have been done on two engines driving a common load via a mechanical gear. The engines are presumed to be linear within their working range. The aim is independently of load variations to get the engines' outgoing angular frequency to be equal to a given reference and to distribute the power between the engines in a given proportion. The report shows that certain arrange

Utmatning på plotter

The task was to write a program for plotter output on a ink jet plotter built at Inst. för Elmät, LTH. This plotter puts dots of ink on a paper fastened to a rotating drum and it must have, for every x-coordinate in its turn, the y-coordinates in rising order where it shall put a dot. 0

Fartygsstyrning vid sjögång

This paper deals with automatic steering of ships under the influence of disturbances from waves. The disturbance has been of two different types, a sinusoidal wave and a disturbance in the yaw rate. We have used both conventional state feedback regulators and adaptive regulators based on least square estimation and minimum variance control. In particular, we have investigated the behaviour of the

Konstruktion av en enkel flygplanssimulator

A simple flight simulator has been built up, using an analog computer to simulate the aircraft dynamics. The dynamics model used, does not represent any particular aircraft. It is nevertheless representative of a large group of conventional aircraft. Simulations clearly show an increased ease in handling the flight simulator, if the pilot has flying experience. This indicates a similarity between
