    Abstract : This doctoral thesis treats three issues in control engineering related to relay feedback and multivariable control systems. Linear systems with relay feedback is the first topic. Such systems are shown to exhibit several interesting behaviors. READ MORE

  4. 2. Gear engagement control for transmissions in hybrid electric vehicles

    Author : Muddassar Piracha; Chalmers tekniska högskola; []
    Keywords : 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;

    Abstract : 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. READ MORE
