| Abstract |
AC-drives based on direct t1ux linkage control (DFLC) allow high dynamic performance combined with simple control schemes. In general the DFCL cannot be adapted alone in motor control without machine voltage measurement. If voltage measurement is not used the measurement of the intermediate voltage and the knowledge of the switching states are used to calculate motor voltages. This easily contains too much error and the stator flux linkage calculation based on the voltage integral becomes unreliable.
Motor current measurement is automatically adopted in modern drives and an inductance based current model for the machine is used to make corrections for the stator flux linkage estimation. Here machine parameters are needed. In this paper the synchronous motor model, parameter identification during drive commissioning and parameter estimation during the drive are briefly introduced. |
