  1. 1. Gear engagement control for transmissions in hybrid electric vehicles

    Författare :Muddassar Piracha; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Noise and wear minimization; Dog Clutch; Hybrid Powertrain; Optimal control; LQI control; Mechanical Synchronizers; Dedicated Hybrid Transmission; Gear shifting; Drivability; Dual Clutch Transmission; Electric Powertrain; Phase plane analysis;

    Sammanfattning : Hybrid and electric vehicles have become very important for vehicle manufacturers due to stricter legislation, government incentives and customers’ growing awareness of the environmental issues. For conventional vehicles, Dual clutch transmissions (DCT) have better shift quality and efficiency than conventional automatic transmissions. LÄS MER

  3. 2. Design of Robust PID Controllers with Constrained Control Signal Activity

    Författare :Olof Garpinger; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; measurement noise; constrained control signal activity; linear systems; disturbance rejection; PID control; process control; Youla parameterized controllers; algorithms and software;

    Sammanfattning : This thesis presents a new method for design of PI and PID controllers with the level of control signal activity taken into consideration. The main reason why the D-part is often disabled in industrial control loops is because it leads to control signal sensitivity of measurement noise. LÄS MER
