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

    Author : Adam Lagerberg; Chalmers University of Technology; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; backlash control; powertrain control; driveability; backlash estimation; model predictive control; optimal control; Automatic control; Reglerteknik;

    Abstract : 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. READ MORE

  4. 2. On Modeling and Control of Flexible Manipulators

    Author : Stig Moberg; Svante Gunnarsson; Anders Robertsson; Linköpings universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System identification; multivariable systems; differential-algebraic equations; robots; manipulators; flexible structures; robustness; position control; nonlinear systems; closed-loop identification; frequency-response methods; industrial robots; robotics; control; feedforward; flexible arms; Automatic control; Reglerteknik;

    Abstract : Industrial robot manipulators are general-purpose machines used for industrial automation in order to increase productivity, flexibility, and quality. Other reasons for using industrial robots are cost saving, and elimination of heavy and health-hazardous work. READ MORE

  5. 3. Modeling and Control of Flexible Manipulators

    Author : Stig Moberg; Svante Gunnarsson; Bruno Siciliano; Linköpings universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Modeling; identification; control; robot manipulator; DAE; flexible multibody dynamics; inverse dynamics; benchmark; Automatic control; Reglerteknik;

    Abstract : Industrial robot manipulators are general-purpose machines used for industrial automation in order to increase productivity, flexibility, and product quality. Other reasons for using industrial robots are cost saving, and elimination of hazardous and unpleasant work. READ MORE

  6. 4. Analysis and Design of Hybrid Control Systems

    Author : Jörgen Malmborg; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lyapunov theory; Mode switching; Multi-controllers; PID control; Simulation; Higher order sliding; Hybrid control; Sliding modes; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Abstract : Different aspects of hybrid control systems are treated: analysis, simulation, design and implementation. A systematic methodology using extended Lyapunov theory for design of hybrid systems is developed. The methodology is based on conventional control designs in separate regions together with a switching strategy. READ MORE

  7. 5. Virtual Sensing of Combustion Quality in SI Engines using the Ion Current

    Author : Nicholas Wickström; Bertil Svensson; Gerard W. Malaczynski; Chalmers University of Technology; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; neural networks; spark ignition; ion current; internal combustion engines; control; estimation; Internal Combustion Engines; Spark Ignition; Estimation; Control; Neural Networks; Ion Current;

    Abstract : Several virtual sensors for combustion quality in spark ignited internal combustion engines are proposed. The virtual sensors estimate combustion quality based on the ion current signal measured in the center of the combustion chamber. Important properties of these sensors are their cost effective implementation and real-time operation. READ MORE
