Control switching table is used to select the voltage command based on the present zone of the flux linkage
that can be determined by the angle.
In the actual rotor reference, the flux linkage
equations of the CPPM machine can be described as :
Mathematical modeling of magnetic field is important for electromagnetic machines, as it could be used to predict output performance, such as flux linkage
, field energy and force generation [13-15].
Therefore derivatives of flux linkage
with respect to time taking into account this dependence has the form
The static flux linkage
curves of the motor, which provides important information about the electromagnetic characteristics of the motor b.
f] is flux linkage
of permanent magnet excitation, [L.
rq]: q-axis component of rotor flux linkage
permanent magnet flux
There is no current controller needed in DTC, because it selects the voltage space vectors according to the errors of flux linkage
The magnetic characteristic is drawn between flux linkage
versus current for various rotor positions.
Magnetization characteristics of the SRM define the relationship between the flux linkage
and the current for any rotor position.
The implementation of the double stator topology eliminates the flux linkage
that increases the output of the PMG as shown in Table 2.
