  2. 6. 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. 7. Modeling and Control of the Paper Machine Drying Section

    Author : Ola Slätteke; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reglerteknik; robotteknik; Automatiska system; Moisture control; Paper-making; Pressure control; Predictive Control; Mid-ranging Control; Wood; Drying Section Modeling; Automation; control engineering; robotics; pulp and paper technology; Pappers- och massateknik;

    Abstract : The topic of this thesis is modeling and control of the last part of the paper machine - the drying section. Paper is dried by letting it pass through a series of steam heated cylinders and the evaporation is thus powered by the latent heat of vaporization of the steam. READ MORE

  5. 8. Fixed-Feedback SISO Adaptive Control

    Author : Magnus Nilsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Two-Degrees-of-Freedom Control; Feedforward Control; Adaptive Control;

    Abstract : Adaptive control is an attractive method to solve control problemssince the tedious task of identifying process behavior to find asuitable design for the controller is taken care of by the adaptivecontroller itself. It may be difficult, however, to guaranteerobustness (in the sense of desired disturbance attenuation andstability margins) for traditional adaptive schemes since theircorresponding loop gain is time varying.

  6. 9. Modeling and Control of Flexible Manipulators

    Author : Stig Moberg; Svante Gunnarsson; Bruno Siciliano; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Modeling; identification; control; robot manipulator; DAE; flexible multibody dynamics; inverse dynamics; benchmark; Automatic control; Reglerteknik;

    Abstract : Industrial robot manipulators are general-purpose machines used for industrial automation in order to increase productivity, flexibility, and product quality. Other reasons for using industrial robots are cost saving, and elimination of hazardous and unpleasant work. READ MORE

  7. 10. Resource-aware Wireless Process Control

    Author : Takuya Iwaki; Karl H. Johansson; Sophie Tarbouriech; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial process control; Networked control systems; Wireless network; Event-triggered control; Electrical Engineering; Elektro- och systemteknik;

    Abstract : To tackle the ever-growing demands on high-quality and cost-effective industrial production, recent developments in embedded sensing, wireless communication, and cloud computing offer great opportunities. Resource-aware reliable wireless communication and real-time control are needed to leverage these technologies. READ MORE
