  1. 1. Control and Estimation of Automotive Powertrains with Backlash

    Författare :Adam Lagerberg; Jönköping University; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; backlash control; powertrain control; driveability; backlash estimation; model predictive control; optimal control; Automatic control;

    Sammanfattning : In automotive powertrains, backlash causes problems with vehicle driveability, specifically at so called tip-in and tip-out maneuvers. These maneuvers may trigger phenomena known in the automotive industry as shunt and shuffle, which are partially caused by the backlash. LÄS MER

  3. 2. Parameter estimation and model based control design of drive train systems

    Författare :Mats Tallfors; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; control; drive train; estimation; identification; mechanical; Signalbehandling; Signal processing; Signalbehandling;

    Sammanfattning : The main control task in many speed-controlled drives is to eliminate or reduce the load speed error caused by the load torque disturbance and reduce oscillations as quickly as possible. This thesis addresses different aspects of identification and control of such resonant elastic systems. LÄS MER

  4. 3. Topics in Machining with Industrial Robot Manipulators and Optimal Motion Control

    Författare :Björn Olofsson; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Two main topics are considered in this thesis: Machining with industrial robot manipulators and optimal motion control of robots and vehicles. The motivation for research on the first subject is the need for flexible and accurate production processes employing industrial robots as their main component. LÄS MER

  5. 4. Modeling and Optimal Control of Heavy-Duty Powertrains

    Författare :Vaheed Nezhadali; Lars Eriksson; Giorgio Rizzoni; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Powertrain; transmission system; optimal control; modeling for control;

    Sammanfattning : Heavy duty powertrains are complex systems with components from various domains, different response times during transient operations and different efficient operating ranges. To ensure efficient transient operation of a powertrain, e.g. LÄS MER

  7. 5. Adaptation and Learning for Manipulators and Machining

    Författare :Olof Sörnmo; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis presents methods for improving the accuracy and efficiency of tasks performed using different kinds of industrial manipulators, with a focus on the application of machining. Industrial robots offer a flexible and cost-efficient alternative to machine tools for machining, but cannot achieve as high accuracy out of the box. LÄS MER
