Abstract
This paper presents a new simplified finitecontrol-
set model predictive control strategy for synchronous
reluctance motors operating in the entire speed
range. It is a predictive control scheme that regulates the
stator flux and the load angle of the synchronous reluctance
motor, incorporating the ability to operate the drive in the
field-weakening region and respecting the motor voltage
and current limits as well as the load angle limitation
needed to operate this type of motor in the maximum
torque per voltage region. The proposed control strategy
possesses some attractive features, such as no need for
controller calibration, no weighting factors in the cost function,
good robustness against parameter mismatch, and
smaller computational cost compared to more traditional
finite-control-set model predictive control algorithms.
Simulation and experimental results obtained using a
high-efficiency synchronous reluctance motor demonstrate
the effectiveness of the proposed control scheme.
