Generic machine identification and maximum efficiency operation of induction machines
Julian Kullick, Christoph M. Hackl
This paper proposes an advanced machine identification method for inverter fed squirrel-cage induction machines, based on steady-state measurements in the rotor flux oriented dq-re…
Speed-sensorless state feedback control of induction machines with LC filter
Julian Kullick, Christoph M. Hackl
A speed-sensorless state feedback controller for induction machines (IMs) with LC filter is proposed. The estimation of speed and remaining states is based on a speed-adaptive obse…
Full- & Reduced-Order State-Space Modeling of Wind Turbine Systems with Permanent-Magnet Synchronous Generator
Christoph M. Hackl, Martin Pfeifer, Korbinian Schechner +2
Wind energy is an integral part of nowadays energy supply and one of the fastest growing sources of electricity in the world today. Accurate models for wind energy conversion syste…
Modeling and control of permanent-magnet synchronous generators under open-switch converter faults
Christoph M. Hackl, Urs Pecha, Korbinian Schechner
The mathematical modeling of open-switch faults in two-level machine-side converters and the fault-tolerant current control of isotropic permanent-magnet synchronous generators are…
