  1. 1. Numerical studies of current profile control in the reversed-field pinch

    Author : Jon-Erik Dahlin; Jan Scheffel; Roberto Paccagnella; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Reversed-Field Pinch; RFP; Current Profile Control; CPC; DEBS; DEBSP; active control; feedback; MHD.; Fusion; Fusion;

    Abstract : The Reversed-Field Pinch (RFP) is one of the major alternatives for realizing energy production from thermonuclear fusion. Compared to alternative configurations (such as the tokamak and the stellarator) it has some advantages that suggest that an RFP reactor may be more economic. READ MORE

  2. 2. A Sequential Control Language for Industrial Automation

    Author : Alfred Theorin; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Grafchart; service oriented architecture; event-driven architecture; flexible production systems; industry 4.0; real-time; FMI; PID;

    Abstract : Current market trends for industrial automation are the need for customizable production, shorter time to market, and powerful global competitive pressure. Based on these trends two challenges have been identified: 1) flexible production systems and 2) integration and utilization of devices and software. READ MORE

  3. 3. Inverter Design for SiC-based Electric Drive Systems with Optimal Redundant States Control of Space Vector Modulation
