  1. 1. Interaction Analysis in Multivariable Control Systems : Applications to Bioreactors for Nitrogen Removal

    Författare :Björn Halvarsson; Bengt Carlsson; Elling Jacobsen; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; activated sludge process; biological nitrogen removal; bioreactor models; control structure design; cost-efficient operation; decentralized control; interaction measures; minimum variance control; multivariable control; wastewater treatment; Automatic control; Reglerteknik; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

    Sammanfattning : Many control systems of practical importance are multivariable. In such systems, each manipulated variable (input signal) may affect several controlled variables (output signals) causing interaction between the input/output loops. LÄS MER

  3. 2. Management control and strategy : a case study of pharmaceutical drug development

    Författare :Fredrika Berglund; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Management control systems; Tight control; Loose control; Interactive control; Diagnostic control; Budget; Portfolio management; Project management; Goals and Objectives systems; Business strategy; Research Development; Pharmaceutical; Computer science; Datavetenskap; Economic Information Systems; Ekonomiska informationssystem;

    Sammanfattning : How are formal management controls designed and used in research & development (R&D)? The purpose of this study is to explain how such systems are designed and used in formulating and implementing strategies in a pharmaceutical product development organisation. The study uses a contingency approach to investigate how the control system is adjusted to the business strategy of the firm. LÄS MER

  4. 3. Enabling and Coercive Control : Coexistence in the Case of Banking

    Författare :Cecilia Ekström; Tobias Johansson; Gabriella Wennblom; Magnus Hansson; Anders Hersinger; Örebro universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Enabling control; coercive control; coexistence of control; attitudinal outcomes of control; management control; regulation; banking;

    Sammanfattning : This thesis focuses on subjects of control and attitudinal outcomes of formalized control in organizations. Previous research have concluded contradicting results of whether formalized control is positive or negative for the employees and propose that not only degree of formalization, but also type of formalization, can explain attitudinal outcomes.

  5. 4. Control and Estimation of Automotive Powertrains with Backlash

    Författare :Adam Lagerberg; Jönköping University; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; backlash control; powertrain control; driveability; backlash estimation; model predictive control; optimal control; Automatic control;

    Sammanfattning : In automotive powertrains, backlash causes problems with vehicle driveability, specifically at so called tip-in and tip-out maneuvers. These maneuvers may trigger phenomena known in the automotive industry as shunt and shuffle, which are partially caused by the backlash. LÄS MER

  7. 5. Event-Based Control and Estimation with Stochastic Disturbances

    Författare :Toivo Henningsson; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; event-based control; stochastic control; event-based estimation; control over networks; quantized measurements; sporadic control; embedded control;

    Sammanfattning : This thesis deals with event-based control and estimation strategies, motivated by certain bottlenecks in the control loop. Two kinds of implementation constraints are considered: closing one or several control loops over a data network, and sensors that report measurements only as intervals (e.g. with quantization).
