… was implemented by dosing carbon dioxide from a gas tank through a mass flow controller. The carbon dioxide in the system can be set to a constant flow to achieve a certain production rate or set to achieve a desired concentration in the exhaled gas. To achieve moisture and …
… to develop a self-report measure regarding human factors, for the air traffic controllers to fill out before they start their working shift. This in order to aid the team leaders in their judgment regarding the air traffic controller's ability to perform at the right safety …
… describes the scientific work of designing and manufacturing an intelligent controller module prototype for automobile trailer connections. The functions of the module are both to drive the lamps and detect failures. The module also contains functions to handle other functions …

En studie om arbetsuppgifter och profession
I vår studie har vi undersökt om svenska controllers utför arbetsuppgifter som är att betrakta som controlleruppgifter. Vi har även undersökt om yrket påminner om en profession eller om den är på väg mot att bli en sådan. Studien är baserad på personliga intervjuer med två …
En fallstudie av informationsbehov hos kundföretag
… that will be answered in this report is, what information is needed for market controllers. The second question investigates how a decision tool that gives the answers to the first question would work. Theories in business and economics written by Jan Lindvall (2001) and …

… Mainly H-infinity and GIMC designs have been compared with an ordinary PID controller. Here it can be shown that both the H-infinity and the GIMC controller yields good disturbance rejection. But both the methods lack in the robustness of model uncertainty.
… control problems, MPC has been used that is a multivariable method. The MPC-controller consists of an optimization problem and therefore MPC can find the optimum control signals in an easy way. Furthermore the boundaries of the control signals can be handled with by-conditions …
