This PhD. thesis deals with a sensorless (encoderless) control of a drive with a synchronous motor with permanent magnets on the surface of a rotor (PMSM). First chapter describes motivations for the presented research and state of the art. A referential vector control in Cart...

This thesis deals with vehicle control system of urban light rail vehicles and their communication in more vehicle trains. The first part contains an analysis and complex description of the control system of existing vehicles and formulates the fundamental deficiencies to ensure the...

The high-power pump and fan applications are among the main electricity appliances in a worldwide scale. Concurrently, these applications have a very significant energy-saving potential arising especially from development of high-power electronics and/or frequency converters enabling energy efficient ...

This thesis deals with the use of power electronics converters for compensation of ground capacitive current (fault current) in the place of one line-to-earth connection at the distribution networks. The main part of the thesis deals with the design and dimensioning of the power&#x...

The dissertation thesis deals with estimation of selected quantities in the field of electric drives and active power filters. The first part of this work is concerned to estimation of velocity and rotor position of two types of electric drives. First drive employs a switched&...
