PMSM control with Rotational Speed (Controlled)

0 votes
Deal all,

I want to use Rotational Speed (Controlled) in my PMSM with inverter model.

However, when I try to use it, there is error same as below

1)State/source dependence in components
- 210208_SingleInverter_speedload/PM Machine/Inertia
- <hidden component>

2)Inconsistent source
- 210208_SingleInverter_speedload/PM Machine/Inertia
- <hidden component>


I thought it is the same as speed load in MATLAB/SIMULINK.

but it isn't

Please let me know how to use it.


I attached error and figure of circuit

Set the machine's Inertia parameter to zero, as shown below.

From the PLECS Documentation: "A speed source may not be short-circuited or connected in parallel with other speed sources, nor may a speed source directly drive an inertia."  Setting the inertia to zero overcomes this issue.

You can also read a bit more about the error message at this link for a deeper understanding.
