| Abstract |
This paper presents a predictive torque and flux
control algorithm for the synchronous reluctance machine. The
algorithm realizes a voltage space phasor pre-selection, followed
by the computation of the switching instants for the optimum
switching space phasors, with the advantages of inherently
constant switching frequency and time equidistant implementation
on a DSP based system. The criteria how to choose the
appropriate voltage space phasor depend on the state of the
machine and the deviations of torque and flux at the end of the
cycle.
The model of the machine has been developed on a d-q
frame of coordinates attached to the rotor and takes into
account the magnetic saturation in both d-q axes and the cross
saturation phenomenon between both axes. Therefore, a very
good approximation of this effect is achieved and the
performance of the machine is improved.
Several simulations and experimental results using a DSP and
a commercially available machine show the validity of the
proposed control scheme. |
