Synchronous Reluctance Machine model parameters

Hi,

I started using the SynRM model from Simscape, particularly using the example of torque control.

I am interested in the option to simulate the nonlinearity of the machine. I can see that there is an option to use Tabulated Ld and Lq, but the model documentation is poor to understand how to use those parameters. SynRM documentation

The mayority of the models I have seen take into account the so called incremental inductances and apparent inductances. So, i wonder if there is some place or sombody that has already used those Tabulated Ld and Lq to know which inductances I have to use and even better if there are more detalis about the nonlinear model itself tha Simscape uses.

Thank you.

The Synchronous Reluctance Machine block is defining the Ld, Lq, and L0 based on the stator self-inductance per phase, the stator inductance fluctuation, and the stator mutual inductance. They are defined in a similar fashion as for the PMSM case. We can use constant or tabulated inductances. In case of tabulated inductances, they will be functions of d and q axis currents allowing us to model phenomena such as magnetic saturation. However, with the tabulated inductances we cannot model harmonics. In case harmonics are of interest it is better to use a FEM parameterized block from Simscape Electrical library instead. I hope this helps.
