  3. 2. Towards a methodology for integrated design of mechatronic servo systems

    Författare :Fredrik Roos; Jan Wikander; Hans Johansson; Hendrik van Brussel; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mechatronics; Servo Systems; Design Methodology; Integrated Design; Construction engineering; Konstruktionsteknik;

    Sammanfattning : Traditional methods for mechatronics design are often based on a sequential approach, where the mechanical structure is designed first, and then fitted with off-the-shelf electric motors, drive electronics, gearheads and sensors. Finally a control system is designed and optimized for the already existing physical system. LÄS MER

  4. 3. On Motion Control of Linear Incremental Hydraulic Actuators

    Författare :Martin Hochwallner; Petter Krus; Kalevi Huhtala; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Linear Incremental Hydraulic Actuator; novel actuator; linear hydraulic actuator; tracking problem; hydraulic servo system; digital fluid power;

    Sammanfattning : Linear Incremental Hydraulic Actuators combine one or more short-stroke cylinders, and two or more engaging/disengaging mechanisms into one actuator with long, medium, or even unlimited stroke length. The motion of each single short-stroke actuator concatenated by the engaging/disengaging mechanisms forms the motion of the linear incremental hydraulic actuator. LÄS MER

  5. 4. Modeling and Linear Quadratic Optimal Control of Wind Turbines

    Författare :Thommy Ekelund; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; periodic system; structural dynamics; yaw control; variable speed; wind turbines; active stall; estimation; LQG; identification;

    Sammanfattning : Control can improve the performance of wind turbines by enhancing the energy capture and reducing dynamic, as well as static, loads. There are several possible configurations of the control system, depending on the available actuators. LÄS MER

  7. 5. Synthesis of a Model-based Tire Slip Controller

    Författare :Stefan Solyom; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LMI; synthesis; hybrid; piecewise linear; ABS; PID;

    Sammanfattning : The Anti-lock Braking System (ABS) is an important component of a complex steering system for the modern car. In the latest generation of brake-by-wire systems, the performance requirements on the ABS have changed. The controllers have to be able to maintain a specified tire slip for each wheel during braking. LÄS MER
