  1. 1. Utility Disturbance Management in the Process Industry

    Author : Anna Lindholm; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; utilities; process control; plant-wide disturbances; availability; buffer tanks;

    Abstract : Use of utilities, such as steam and cooling water, is very common at industrial sites. Utilities are often shared between several production areas, and a disturbance in the supply of a utility is therefore likely to affect a large part of the production site, and cause great loss of revenue.

  2. 2. Averaging level control in the presence of frequent inlet flow upsets

    Author : Peter Rosander; Alf J. Isaksson; Johan Löfberg; Morten Hovd; Linköpings universitet; []
    Keywords : Averaging level control; PI control; Surge tanks; Optimal control; Robust MPC; Process control;

    Abstract : Buffer tanks are widely used within the process industry to prevent flow variations from being directly propagated throughout a plant. The capacity of the tank is used to smoothly transfer inlet flow upsets to the outlet. Ideally, the tank thus works as a low pass filter where the available tank capacity limits the achievable flow smoothing. READ MORE

  3. 3. Selected Applications of Switched Capacitor Circuits : RF N-Path Filters and ΣΔ Modulators

    Author : Fahad Qazi; Jerzy Dabrowski; Atila Alvandpour; Henrik Sjöland; Linköpings universitet; []

    Abstract : Electronic circuits based on switches and capacitors have been used in various applications for several decades. The common switched capacitor (SC) circuits have made their career primarily in analog filters and data converters due to high immunity to capacitance mismatch in integrated circuit (IC) technologies.
