  2. 1. Modeling, Control and Optimization of theTransient Torque Response in DownsizedTurbocharged Spark Ignited Engines

    Author : Oscar Flärdh; Håkan Hjalmarsson; Jonas Mårtensson; Per Tunestål; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engine modeling; Engine control; Transient torque response; Downsizing; Transient optimization;

    Abstract : Increasing demands for lower carbon dioxide emissions and fuel consumption drive technological developments for car manufacturers. One trend that has shown success for reducing fuel consumption in spark ignited engines is downsizing, where the engine size is reduced to save fuel and a turbocharger is added to maintain the power output.

  4. 2. Modelling, analysis and experimentation of a simple feedback scheme for error correction control

    Author : Oscar Flärdh; Karl H. Johansson; Mikael Johansson; Bo Bernhardsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Network Control; Error Correction; Multiple-Input Describing Function; Extremum Seeking Control; Sensor Network Experiments; Automatic control; Reglerteknik;

    Abstract : Data networks are an important part in an increasing number of applications with real-time and reliability requirements. To meet these demands a variety of approaches have been proposed. Forward error correction, which adds redundancy to the communicated data, is one of them. READ MORE

  5. 3. Fuel-Efficient Look-Ahead Control for Heavy-Duty Vehicles with Varying Velocity Demands

    Author : Manne Held; Jonas Mårtensson; Oscar Flärdh; Ardalan Vahidi; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; look-ahead control; optimal control; powertrain control; advanced driver assistance systems; Electrical Engineering; Elektro- och systemteknik;

    Abstract : The fuel consumption of heavy-duty vehicles can be reduced by using information about the upcoming road section when controlling the vehicles. Most manufacturers of heavy-duty vehicles today offer such look-ahead controllers for highway driving, where the information consists of the road grade and the velocity only has small variations.
