  1. 1. Solving a Dead-lock Problem of NFO Sinus

    University essay from Institutionen för systemteknik

    Author : Henrik Engdahl; [2007]
    Keywords : sensorless motor control; asynchronous AC motor; field orientation;

    Abstract : This thesis presents, analyzes and suggests solutions to the dead-lock problem of the sensorless variable speed drive NFO Sinus. Friction, measurement, parameter estimation and quantization effects are believed possible origins of this problem and is hence studied. READ MORE

  4. 3. Nonlinear Modeling of Locomotive Propulsion System and Control

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Henrik Sandberg; [1999]
    Keywords : Technology and Engineering;

    Abstract : In this report the motor side of a converter driven AC-locomotive is studied and modeled. The motor side consists of an asynchronous electrical engine, an indirect self controller, a voltage converter, a Pulse Width Modulator(PWM) and the train mechanics. The converter is supplied with voltage from a DC-link. READ MORE
