| Abstract |
Methods for estimation of the parameters in the inverter
and the PM motor, based on special designed experiments,
are given. Input to the system is the reference values for the stator
voltages given as duty cycles for the Pulse With Modulated
power device. The system output is the measured stator currents.
Inverter parameters, stator resistance and inductance are measured
at stand-still before the initial start-up of the drive. The
strength of the permanent magnet is measured during a initial
manual start-up of the drive. The measured parameters are used
in a field oriented control system and the performance is experimentally
verified. |
