  1. 6. Analysis of Active Gyro Based Roll-Stabilization of Slender Boat Hulls

    University essay from KTH/Marina system

    Author : Tao Zhang; [2014]
    Keywords : ;

    Abstract : Currently, traffic congestion often happens in big cities every day. People demand a new conceptual vehiclewhich has a slender shape to reduce space, lightweight structure to decrease the fuel consumption andinnovative technology to adapt for multiple transportation conditions.

  3. 7. Modeling of Engine and Driveline Related Disturbances on the Wheel Speed in Passanger Cars

    University essay from Institutionen för systemteknik; Tekniska högskolan

    Author : Robert Johansson; [2012]
    Keywords : Wheel speed disturbance; driveline model; engine model; torsional vibration; diesel;

    Abstract : The aim of the thesis is to derive a mathematical model of the engine and driveline in a passenger car, capable of describing the wheel speed disturbances related to the engine and driveline. The thesis is conducted in order to improve the disturbance cancelation algorithm in the indirect tire pressure monitoring system, TPI developed by NIRA Dynamics AB. READ MORE

  4. 8. Project Solaris – Construction of Solar Powered UAV Prototype

    University essay from Akademin för innovation, design och teknik

    Author : Magnus Johansson; [2011]
    Keywords : Flight testing; empennage; solaris; differentiated thrust;

    Abstract : Abstract To control an un-swept flying wing is problematic in some ways. One of the problems is that when the wing experiences a disturbance in yaw, it does not, since it has no tail, generate any torque in the opposite direction as a plane with a vertical stabilizer does. READ MORE

  5. 9. Torque Sensor Free Power Assisted Wheelchair

    University essay from Sektionen för Informationsvetenskap, Data– och Elektroteknik (IDE)

    Author : Jonas Johansson; Daniel Petersson; [2007]
    Keywords : torque sensor free; power assisted wheelchair; velocity disturbance controlled; power assisting; wheelchair; digital control; assisting power; motorized; sensor free; disturbance controlled; intelligent; rotational encoder; rotary encoder; electrical motors; development board; controller card;

    Abstract : A power assisted wheelchair combines human power, which is delivered by the arms through the pushrims, with electrical motors, which are powered by a battery. Today’s electric power assisted wheelchairs use force sensors to measure the torque exerted on the pushrims by the user. READ MORE

  6. 10. Torque Modeling and Control of a Variable Compression Engine

    University essay from Institutionen för systemteknik

    Author : Andreas Bergström; [2003]
    Keywords : Technology; Torque control; SVC; Variable compression; IMC; MVEM; TEKNIKVETENSKAP;

    Abstract : The SAAB variable compression engine is a new engine concept that enables the fuel consumption to be radically cut by varying the compression ratio. A challenge with this new engine concept is that the compression ratio has a direct influence on the output torque, which means that a change in compression ratio also leads to a change in the torque.
