   Abstract : Popular Abstract in Swedish Återkoppling är en fundamental princip inom reglertekniken. Genom att mäta vissa variabler kan andra påverkas så att ett system uppför sig på önskat vis. Denna doktorsavhandling behandlar två typer av återkoppling: reläåterkoppling och flervariabel återkoppling. READ MORE

5. 3. Ammonium Feedback Control in Wastewater Treatment Plants

   University dissertation from Uppsala : Acta Universitatis Upsaliensis

   Author : Linda Åmand; Uppsala universitet.; Uppsala universitet.; [2014]
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aeration control; ammonium feedback control; biological nitrogen removal; full-scale experiments; gain scheduling control; PI control; process control; repetitive control; wastewater treatment; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

   Abstract : The aeration process is often the single largest consumer of electricity in a wastewater treatment plant. Aeration in biological reactors provides microorganisms with oxygen which is required to convert ammonium to nitrate. Ammonium is toxic for aqueous ecosystems and contributes to eutrophication.

6. 4. Tools for Autonomous Process Control

   University dissertation from Department of Automatic Control, Lund Institute of Technology (LTH)

   Author : Anders Wallén; Lunds universitet.; Lund University.; [2000]
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sequential control; software architectures; fast set point response; spectral estimation; frequency domain identification; relay feedback; non-linear system identification; Autonomous Control; Process Control; Grafcet; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

   Abstract : There is an ongoing trend towards higher automation level in process control systems. The purpose of a plant is to manufacture some product at a high production rate with a consistent quality, while minimizing the use of resources in terms of energy consumption, raw material and labor.
