  4. 22. Iterative Road Grade Estimation for Heavy Duty Vehicle Control

    Author : Per Sahlholm; Karl Henrik Johansson; Jonas Sjöberg; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; road grade; estimation; heavy duty vehicle; Kalman filter; automatic control; Automatic control; Reglerteknik;

    Abstract : This thesis presents a new method for iterative road grade estimation based on sensors that are commonplace in modern heavy duty vehicles. Estimates from multiple passes of the same road segment are merged together to form a road grade map, that is improved each time the vehicle revisits an already traveled route. READ MORE

  5. 23. Look-ahead control for fuel-efficient and safe heavy-duty vehicle platooning

    Author : Valerio Turri; Karl H. Johansson; Petros Ioannou; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; platoon; platooning; optimization; optimal control; model predictive control; automatic control; fuel efficiency; intelligent transport systems; automated driving; cooperative; dynamic programming; trucks; heavy-duty vehicles; safe platooning; fuel-efficient platooning; distributed model predictive control; MPC; vehicle-following; pulse and glide; Vehicle and Maritime Engineering; Farkostteknik;

    Abstract : The operation of heavy-duty vehicles at small inter-vehicular distances, known as platoons, lowers the aerodynamic drag and, therefore, reduces fuel consumption and greenhouse gas emissions. Tests conducted on flat roads have shown the potential of platooning to reduce the fuel consumption of about 10%. READ MORE

  6. 24. Modeling and Control of Bilinear Systems : Application to the Activated Sludge Process

    Author : Mats Ekman; Bengt Carlsson; Claes Breitholtz; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bilinear systems; modeling; optimal control; parameter estimation; errors-in-variables; activated sludge process; Automatic control; Reglerteknik;

    Abstract : This thesis concerns modeling and control of bilinear systems (BLS). BLS are linear but not jointly linear in state and control. In the first part of the thesis, a background to BLS and their applications to modeling and control is given. READ MORE

  7. 25. Estimation-based iterative learning control

    Author : Johanna Wallén; Mikael Norrlöf; Svante Gunnarsson; Jian-Xin Xu; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Iterative learning control; estimation; industrial robotics; performance; Automatic control; Reglerteknik;

    Abstract : In many  applications industrial robots perform the same motion  repeatedly. One way of compensating the repetitive part of the error  is by using iterative learning control (ILC). The ILC algorithm  makes use of the measured errors and iteratively calculates a  correction signal that is applied to the system. READ MORE
