AN IMPROVED SENSORLESS CONTROL
SYSTEM OF PERMANENT MAGNET SYNCHRONOUS MOTOR
To improve the performance of
permanent magnet synchronous motor sensor less control system, the phase offset
caused by the low pass filter must be considering. In this paper, to apply
the linear control theory to PMSM system. The introduced control strategy is based
on reduced-order observer and adaptive velocity estimation, then proposed a
method to compensate the phase offset by group time delay. With proper pole
locations of the observer, stability of the position estimation is guaranteed,
and stability of the adaptive velocity estimation is also guaranteed by Popov's
hyper stability theory. The effectiveness of the method is verified through the
SIMULINK modeling and simulation.
