In industrial Control systems PID-Control remains the prevalent strategy, also for processes that would benefit from model based Control. The purpose of this thesis is to evaluate whether model based Control can be readily implemented in an industrial Control system. To this end a simulated surge tank with a simulated industrial Control system is studied. For evaluation two scenarios with specified objectives are selected.Following a review of LQR and versions of MPC, Predictive Functional Control (PFC) is considered the most suitable for implementation. PFC is a form of MPC developed with industrial applications in mind and therefore has several advantages for implementation in an industrial Control system.

Title: Co-operative, prevent or complement? - An essay on the relationships between Control systems. Authors: Kim Eriksson and Victoria KarlssonPurpose: The essay aims to describe the relations between Control systems and how they related to each other, based on an operationalization of the Control systems. Research question: What are the Control systems relations to each other? With regards whether Control systems co-operative, prevents and/or complement each other.Theoretical framework: The essays theoretical framework is based on Malmi and Browns (2008) description of five different Control systems and Control mechanisms associated with each Control system.   Research methodology: The method was based on three different data collection methods. These methods were observations, documentation, and semi-structured interviews.Conclusions: It is concluded that the Control systems has comprehensive relations. Control systems have more, than one, relation to each other..

The secondary Control must be part of the production plan, since the capacity will bedeployed in advance, just as the primary Control. The activation of the new frequencyControl should be preformed in Vattenfall's operations centers (DC) to minimizecommunication delay. Vattenfall needs to work towards a more holistic optimizationsystem. The main issue for Vattenfall Generation is not how we produce but ratherwhen, which is done with creation of bids. This is where there is the mostopportunity for improvement.

Studier har visat att det finns ett samband mellan syskonplacering och locus of Control, medan andra studier inte funnit något samband. Syftet med denna studie är att undersöka relationen mellan syskonplacering, kön och locus of Control ur ett hälsoperspektiv hos gymnasieelever i årskurs 3. I undersökningen deltog 147 gymnasielever ifrån fem skolor i Kronobergs län. Resultatet visade att kön och syskonplacering samvarierade med intern health locus of Control (F= 3,01;p< 0,03; ES= 6,2) och att syskonplacering och kön tillsammans inte visade någon signifikant inverkan på extern health locus of Control (F= 2,20;p=<0,09; ES= 4,6). Fyndet kan indikera att manliga mellanbarn i större utsträckning strävar efter en intern health locus of Control än kvinnliga mellanbarn.Nyckelord: Syskonplacering, health locus of Control, intern- och extern locus of Control, kön..

This thesis aims to develop a Control system for measuring electromagnetic compability (EMC). This has meant that a Controller designed around an ATmega8 microController has been manufactured and programmed. It has also meant the development of a comprehensive Control software in the program MATLAB. The Control system has been tested with satisfactory results and can now, monitor and Control measurements of the EMC-type..

The Control of indoor temperature must be able to handle large time constants and both measureable disturbances like outdoor temperature, and non-measurable disturbances, like waste heat from appliances. Due to cheaper microControllers (small computers with designated tasks) with better performance, more advanced and computation-demanding methods for Control can be used.In this thesis, Generalized Predictive Control (GPC) has been implemented and tested on a theoretically derived model of a house. GPC states that a model of the system is estimated in every sample, and the Control is carried out simultaneously, based on predictions of the model. Disturbances like solar radiation can be estimated and used in the Control as well. The Control signals are determined by quadratic programming, which makes it possible to consider conditions, for example limitations on the Control signals.GPC requires a number of parameters to be defined, like model order and Control signal penalty, but is relatively robust for variations in them.

The purpose with this paper is that trough a description of the management Control at Jitech AB find out if traditional management Control have been abandoned for benefit for modern management Control and in which extent the transition have happened. Further is the second purpose with this paper to find out which decisions that lies behind the design of the management Control and how these are in opposition to with the theory..

This thesis has been conducted at Saab Bofors Dynamics AB. The purpose was to investigate if a non-linear missile model could be stabilized when the optimal Control signal is computed considering constraints on the Control input. This is particularly interesting because the missile is Controlled with rudders that have physical bounds. This strategy is called Model Predictive Control. Simulations are conducted to compare this strategy with others; firstly simulations with step responses and secondly simulations when the missile is supposed to hit a moving target.

The aim of this thesis is to examine how salesperson Control can be exercised in a retail store environment. A case study has been performed on a Swedish fashion company emphasizing the relationship between the company?s upper level management and their retail store operations in order to describe, analyze and classify the prevailing management Control mechanisms. The paper presents an agency theoretical approach to the relationship applying behavior- and outcome based Control theory, performance measurement theory and incentives theory in order to give a comprehensive image of the Control system. The main finding is that the company?s management Control system as applied to the sales force in its retail stores can be categorized as mainly behavior-based despite several explicit outcome-based features..

Problem: What are the characteristics of Polykemi?s management Control system and how is it affected by growth? Purpose: To describe and analyse the management Control system of a medium-sized family-owned company from the perspective of Simons? Levers of Control. Research design: An abductive, interview-based case study of Polykemi AB. Conclusion: Polykemi?s management Control system is primarily a traditional one which is rather strong in terms of Levers of Control.

This master thesis deals with problems in the arc length Control in Pulsed MIG/MAG Welding. The main problem is that it is not possible to measure the arc length. In the present solution the voltage over both the electrode and the arc represents the arc length. To improve the arc length Control a model of the electrode melting has been built. One output from the model is the voltage over the electrode and with this voltage together with the measured voltage it is possible to calculate the voltage over just the arc.

This study aims to examine the effect management Control systems have on which goals health centers prioritize. The management Control systems of one privately owned and one publicly owned health center have been studied through a qualitative case study. Robert Simons (1995) framework with four levers of Control (diagnostic Control systems, interactive Control systems, belief systems and boundary systems) has been used to structure the study. For both health centers we found a conflict of interest mainly between the diagnostic Control system and the beliefs system, where the diagnostic Control system is biased towards quantitative goals and the beliefs system is mainly biased towards qualitative goals. However, despite the unbalanced levers of Control the studied health centers have been able to reach a well functioning compromise between quantitative and qualitative goals..
