Medium level programming languages for micro processors

This report of master thesis describes two programming languages for micro processors namely: MLP for Intel 8008 developed at CERL, Great Britain and HILP 80 for Intel 8080 developed as master thesis at Lund Institute of Technology. The compilers generate assembly code and are intended to be implemented on a host computer. The compilers are based on the macro processor STAGE 2, and need about 15 K

Dimensionering av digital regulator för reglering av utloppsarean till turbojetmotor

This report provides results of simulations and a few different methods of designing controllers for sampled data systems. In the report a mathematical model of the exhaust nozzle control of a turbofan engine is shown. During the simulations great attention has been paid to the sensitivity of the regulators against variations of the parameters in the system, and the behaviour of control signal an

Dynamikstudier på ett ångkraftverk

The goal of this work is to build a dynamic model for a steam power plant, using frequency and step-response analysis and use it for construction of an automatic controlling system. The model is to simulate all the variables necessary for controlling with reasonable accuracy. By using measurements at a power plant in x 14rebro, the transfer functions for the most important steam pressures and pro

Reglermodell för ubåträddningsfarkost

Kockums Mekaniska Verkstad, Malmö, is building a submarine rescue vehicle (URF) for military and civilian purposes. The theoretical and experimental background for the dynamics of the submarine is incomplete. One miss is for example a total model for the submarine, that is, what happens when you pull the control lever. We have constructed such a model suitable for simulations on a computer in the

Dynamiska modeller för, samt simulering och temperaturreglering av överhettarsystem på en turbintanker

Our task has been to design a dynamic model for a super heater of a marine steam boiler on a turbine vessel. We have also investigated different methods for control of the temperature of the outflowing steam by computer simulation. The aim has been to make the regulation faster at different load and disturbance. In our models we have described characteristics for valves, regulators and steam pipe

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
