  2. 11. Estimation and Control of Resonant Systems with Stochastic Disturbances

    Author : Peter Nauclér; Torsten Söderström; Anders Robertsson; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vibration control; stochastic control; stochastic systems; feedforward control; Wiener filtering; Kalman filtering; wave separation; unbalance estimation; nonlinear regression; Automatic control; Reglerteknik;

    Abstract : The presence of vibration is an important problem in many engineering applications. Various passive techniques have traditionally been used in order to reduce waves and vibrations, and their harmful effects. Passive techniques are, however, difficult to apply in the low frequency region. READ MORE

  4. 12. Industry applications of multivariable control

    Author : Wolfgang Birk; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

    Abstract : In the face of environmental regulations, optimization of industrial processes becomes necessary. This doctoral thesis summarizes the results of three application-driven projects in automatic control that were aimed at process optimization in the steel industry. READ MORE

  5. 13. Backstepping and control allocation with applications to flight control

    Author : Ola Härkegård; Torkel Glad; Marc Bodson; Linköpings universitet; []
    Keywords : backstepping; control allocation; flight control; control theory; nonlinear control; reglerteknik; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : In this thesis we study a number of nonlinear control problems motivated by their appearance in flight control. The results are presented in a general framework and can also be applied to other areas. The two main topics are backstepping and control allocation. READ MORE

  6. 14. Modeling, Control and Optimization of a Plate Reactor

    Author : Staffan Haugwitz; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mid-ranging control; transition control; start-up; exothermic reaction; chemical reactor; modeling; process control; optimization; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Abstract : A new chemical reactor, the Alfa Laval Plate Reactor, is being developed by Alfa Laval, a Swedish world-leading heat exchanger company. The plate reactor combines the high-heat-transfer capabilities of plate heat exchangers with the efficient mixing and reaction control typical of microreactors. READ MORE

  7. 15. Active Noise Control in Aircraft : Algorithms and Applications

    Author : Sven Johansson; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; active noise control; feedforward control; filtere-x lms algorithm; complex lms; multichannel system; multiple reference; aircraft; headset;

    Abstract : The thesis consists of five papers which are divided into three main parts. Parts A and B deal with active noise control in a propeller aircraft application, whereas Part C deals with active noise control in a helicopter application. READ MORE
