An interactive computer program for design of plats via simulation of product flow in a dairy has been developed at ALFA-LAVAL in Lund. The users of the program have suggested a number of improvements in order to simplify the interaction between the program and the user. This report describes the decided solution strategy and how it has been inserted into the existing program, and furthermore how
Working on the Airbus A310 flight management computer system
Elektroniska bromssystem - en lämplighetstest
During recent years, the application of electronic devices to road vehicles has grown tremendously. Increased environmental concern and requirements on fuel economy, comfort and safety have created a need for compact and advanced micro-computer technology. A vehicle is a problematic environment for electronic devices due to dust, damp, vibrations, noise and glitches. This report first gives an o
LQG-regulator för flygplan
A method of resign for multivariable systems is presented. It is used in an application design of a controller for an advanced aircraft. The main design criteria, singular values plot, is discussed in detail. A must for the use of the method is that computer assistance is available. Two different interactive program packages allowing LQG-design are presented and somewhat compared.
A Self-tuning PID-Controller for Systems with Time-varying Time Delay
Modell och styrning av tvåmotorsprocess med kopplade likströmsmotorer
The goal of this work is to build a dynamic model for a scalemodel of a process with coupled drives, using frequency and step-response analysis and to construct a regulator for this model. The scalemodel, constructed by the English company Tecquipment, is primarily intended for laboratory use by students. The main problem is to reduce the interaction between the dynamics of the tension and the dy
En självinställande regulator för frekvensreglering av kraftsystem med högspänd likström
A self-tuning controller for frequency control of power systems by HVDC. One of the advantages of High Voltage Direct Current, HVDC, is the possibility to control the power flow between different parts of an A.C. network. This property is being used when disturbances in the frequency, caused by load variations, is eliminated. Simulation studies on a physically scaled model of the "Gotland-tr
