  2. 1. Optimal Control of Electric Bus Lines

    Author : Rémi Lacombe; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Eco-driving; Electric buses; Bus bunching; Nonlinear programming; Optimal control; Model predictive control;

    Abstract : Bus lines are inherently unstable systems, where any delay tends to be further amplified by the accrued passenger loads encountered at stops downstream. This self-reinforcing mechanism, when combined with the multiple sources of disturbances of an urban environment, can lead to the problem of bus bunching. READ MORE

  4. 2. On robust and optimal control : with real time aspects

    Author : Torbjörn Norlander; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

    Abstract : This thesis deals with several issues in realistic design of control systems, both from a practical and a theoretical point of view. This is done in three papers which are preceded by an introduction and a short discussion on future research on time-varying delays. The first paper discusses the importance of reliable sensors in control systems. READ MORE

  5. 3. On Optimal Mission Planning for Vehicles over Long-distance Trips

    Author : Ahad Hamednia; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stochastic dynamic programming; Optimal control; Logistics planning; Thermal and charging management; Model predictive control; Mission planning;

    Abstract : This thesis proposes a mission planner for vehicles over long-distance trips, for finding the optimal trade-off between trip time, energy efficiency, and driver comfort, subject to road information, traffic situations, and weather conditions. The mission planner consists of three components, i.e. READ MORE

  6. 4. Prediction horizon requirement  in control and extreme load analyses for survivability : Advancements to improve the performance of wave energy technologies
