  1. 16. An Isolated Integrated Charger for Electric or Plug-in Hybrid Vehicles

    Författare :Saeid Haghbin; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Galvanic Isolation; Grid Synchronization; Vehicle Applications; Integrated Battery Charger;

    Sammanfattning : For electric and hybrid vehicles using grid power to charge the battery, traction circuit components are not normally engaged during the charging time, so there is a possibility to use them in the charger circuit to have an on-board integrated charger.In this Licentiate thesis, an isolated high power integrated charger is proposed, designed and constructed based on a special ac machine with a double set of stator windings called motor/generator.

  3. 17. Flexible Scheduling Methods and Tools for Real-Time Control Systems

    Författare :Dan Henriksson; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Model Predictive Control; Simulation Tools; Delay Compensation; Feedback Scheduling; Real-Time Control;

    Sammanfattning : This thesis deals with flexibility in the design of real-time control systems. By dynamic resource scheduling it is possible to achieve on-line adaptability and increased control performance under resource constraints. The approach requires simulation tools for control and real-time systems co-design. LÄS MER

  4. 18. Model Based Powertrain Control - Damping of Oscillations in a Heavy Duty Vehicle

    Författare :Maria Bruce; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Torsional resonances in the vehicle powertrain are undesired phenomena in automotive vehicles, since they cause longitudinal oscillations in the vehicle, which affect the driveability in a negative way and cause mechanical wear. It is the damping of these torsional resonances that has been the goal for this research work. LÄS MER

  5. 19. Towards active engine mounting systems for commercial vehicles: modeling and analysis

    Författare :Hoda Yarmohamadi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nonlinear dynamic stiffness and damping; Actuators; Computational model; Conventional engine mount; Vibration isolation; Adaptronic mounting system; Model errors tolerance; Commercial vehicles;

    Sammanfattning : The vehicle engine mounting system, which consists of several mounts connecting the engine to the vehicle structure, not only supports the weight of the engine but also isolates the noise, vibration and the transmitted forces to the vehicle structure. At present conventional elastomeric mounts are widely used in engine mounting systems for commercial vehicles. LÄS MER

  7. 20. Study of Induction Machines with Rotating Power Electronic Converter

    Författare :Yanmei Yao; Chandur Sadarangani; Zi-Qiang Zhu; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Brushless induction machine; efficiency improvement; optimum efficiency; rotating power electronic converter; unity power factor; variable power factor; wound rotor induction machine; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : This thesis investigates a novel induction machine topology that uses a rotating power electronic converter. Steady-state and dynamic performance of the topology is studied to understand its operational principle. Furthermore the potential of improving its efficiency and power factor is investigated. LÄS MER
